Bai Su and Bai Zhi were told by Su Qinghuan in advance to stay outside. Luo Qian looked at the two of them as calm as an old man. He could not help coming forward and said, "Two girls, can you reveal one or two things, madam?" Bai Su said with an expressionless face, "How can we slaves know about our masters?" Luo Qian did not know why he was a little afraid of Bai Su and shyly shut up. What happened to the hand? Lu Qi put Su Qinghuan on the chair, raised her arm, and sure enough saw her right hand wrapped in gauze. Today, when the master came, I accidentally knocked over the teacup when I refilled the tea for him, and only scalded a little. She gestured at the position on the back of her hand. "I was afraid of leaving a scar, so I washed it with cold water and took the medicine. In fact, it didn't matter. I was afraid that the scar was too ugly." Only then did Lu Qi breathe a sigh of relief. He frowned at her eyes and said, "What happened when I bowed my head and admitted my mistake just now?" With a sly smile, Su Ching-huan stretched out his hand to flatten his brows and said, "In order to give you some face in front of outsiders.". My uncle said, you are the commander in chief of the army, and you can't always put your face under your feet. He has given me the ability to cross in the nest! Su Qinghuan couldn't help laughing at the thought that Doctor Linghu sternly called her "cross in the nest". Unconvinced, Lu Qi narrowed his eyes and looked at her threateningly. "Is it that simple?" The smile on Su Qinghuan's face solidified, biting his lips, his eyes slowly turned red, and he looked straight at Lu Qi with deep guilt in his eyes. Talk Lu Qi was so anxious that his heart jumped out and he held her shoulder with both hands, so strong that he almost crushed her. What exactly did he say to you? All right, if you don't tell me, I'll go find him! "No, you let me slow down and think about what to say." Su Qinghuan pulled him. The two men looked at each other and were silent for a long time. I really want to apologize to you. Su Qinghuan bit his lip. She rarely bowed her head, but she admitted her fault. Doctor Linghu's words echoed in her ears. I have always looked up to you, not only because you have high medical skills and a good heart, but also because you have a pleasant personality, do not despise yourself because you are a woman, and do better than many men. But if you think about it carefully, did you handle it right? At that time, she was still unconvinced. "Nothing happened to them, so we are all right," she said. Doctor Linghu asked her in reply, "If Qin Fang is really fascinated by the medicine and has a thing with that girl, but he is willing to admit his mistake, what will you do?" Su Qinghuan said frankly: "Then we are finished." Doctor Linghu knocked her on the arm with a tobacco pouch pot. "Ungrateful and foolish." Su Qinghuan is very aggrieved: "I do not owe him, even if he is kind to me, I also returned.". Is it tolerable, but what is intolerable? Martial Uncle, Drive in racking system , you still don't understand me. "I ask you," Linghu doctor looked at her, eyes are unprecedented serious, "when you were killed by Cheng Xuan's wife, almost lost, how did Qin Fang do? Is he done with you? You were wronged to death at that time. He created the Chang'anmen Rebellion for you and was criticized by all the people in the world. Okay, you're the victim. I'm not talking about you. Then why are you wronged again when you change your position today? Qin Fang is not uncomfortable? Just because he's a man, just because he respects you and loves you, he deserves it? If Qin Fang makes a mistake on his own initiative, I will scold him to death. But he is also a victim. Why do you have the right to rub salt into his wounds with this matter? "Ching Huan, your idea really disappoints me. What's the difference between you and those secular women?" "If you had been broken, would Qin Fang have abandoned you?" "Then why are you so selfish?" In fact, I know that he will not be as rough on you as outsiders speculate. He regards you as the tip of his heart. I can see and feel it. But I am afraid that you will be lucky. People's life is too long, you will encounter a lot of things, what is this? He loves you, and you should be more considerate of him. Su Qinghuan remembered the grievance of Lu Qi on the day of the incident, and she even foolishly thought that he was acting cute and laughed it off. Now that I think about it, his heart is really very sad, he and she, both have cleanliness, want to defend each other like jade. How disgusting and uncomfortable he was when something like that happened. But what did she do? Su Qinghuan wished he could slap himself twice. Doctor Linghu was right. When something like that happened to her, she was pointed at by the whole capital and regarded as a laughing stock. It was Lu Qiyi who shouldered all the criticisms and protected her firmly under his wings and healed the wound. So when she mentioned it again today, she could also face it lightly. But what about her? Doctor Linghu said, "Martial Uncle is all alone. What do you think?"? At that time, there was also a woman, as proud as you, who left me just because of misunderstanding. I don't blame her, I just regret that I really wanted to be with her for the rest of my life. Su Qinghuan burst into tears. Probably, a little bit, plus a thought of the difference, she also became that she, also almost let Lu Qi become another lonely Linghu doctor. Chapter 423 lifting of the ban. After listening to Su Qinghuan, looking at her tearful appearance, Lu Qi's heart seemed to be immersed in sour water, sour and soft. He drew out her veil to wipe away her tears and said with a smile, "Fool, I have always known that you are jealous.". You don't have to be so generous, and you don't have to be so hard on yourself. I am a man, always do more than you, otherwise, how can I feel? I'm sorry, I'm sorry. Su Qinghuan threw himself into his arms and sobbed, "When I think of the lonely way my uncle talked to me, and think that we might become like that, I feel very sad.". I was wrong. I shouldn't have talked to you like that. Give me another chance and I'll tell you again! "Well, you're really right. At least I don't think you did anything wrong. Don't cry. It makes my heart confused." 。 omracking.com

Bai Wanjian opened his eyes and his face was livid, thinking that the other party had spared my life. His intention was to take their son to walk, and he was defeated. How could he be beaten and stopped again? What's more, even if he fought again, his two fists could not defeat his four hands. After all, he fought with his wife. Remembering that his beloved daughter had been killed by his husband and wife's son, he led the people to the Central Plains. He lost seven younger martial brothers and sisters in the Changle Gang. Shi Zhongyu got and lost, and the snow mountain swordsmanship that he had been conceited all his life was no match for Xuansu's two swords. His reputation was lost in the running water all his life. Suddenly. By this time Huyan Wanshan and Wen Wanfu had heard the news and returned to the temple. Seeing that the Elder Martial Brother had been defeated, they shouted in unison, "They fight the few with the many. Can't we follow suit?" Eighteen men, each with a long sword, attacked Shi Qing and Min Rou from all directions. "Elder Martial Brother Bai," said Shi Qing, "my husband and I have joined hands. Although we have a slight advantage, we have not yet won or lost. Take it!" With these words, Tingjian stabbed Bai Wanjian. In the capacity of Bai Wanjian, since the other party had just spared his own life, he could not fight again. But Shi Qing himself sent his sword, but he could parry it. "Well," he said to himself, "I'll fight you to the death one by one." He immediately raised his sword and slanted back. Bai Wanjian and Shi Qing started the fight, and the situation was different. Just now he was one against two,long span shelving, and he was pinned down everywhere. The defense was extremely tight, but it was difficult to give full play to the counterattack. When attacking Shi Qing, he had to prevent Min Rou from attacking. When the sword stabbed Min Rou, he had to respond to Shi Qing. At this time, one person fights one person, single sword to single sword, and he is ashamed of the defeat of Shicai. He immediately makes the seventy-two snow mountain swordsmanship incisively and vividly, and attacks with all his strength. Shi Qing was secretly surprised: "There is nothing under the name of'Cold Northwest ',Pallet rack supplier, but it is a first-class swordsman in the world!" Lifting his spirits, he displayed all that he had learned in his life. He thought to himself, "I want to teach you to know that my Shangqingguan swordsmanship is not inferior to your Xueshan Sect.". I have ordered my son to worship at the door of your school, but it has another profound meaning. Don't be arrogant and think that I, Shi Qing, am not as good as you, Bai Wanjian. The two men really met their opponents in this fight. Bai Wanjian's moves are swift and violent, and the sword moves vertically and horizontally. Shi Qing, however, is as calm as a mountain, and the law is rigorous. Bai Wanjian changed his swordsmanship more than ten times in a row, but he couldn't get the upper hand all the time. He was secretly surprised: "This man's swordsmanship is even higher than his reputation. But why did he order his son to worship under this sect?" Then he thought, "Just now I was defeated by the sword. It can be said that two fists are hard to defeat four hands. Now I'm fighting alone. If I lose one and a half moves again, the Snow Mountain Sect will really lose its reputation.". I must seize his vital point and spare his life, or I will not be able to wipe out my shame. As soon as he is eager to win, pipe cantilever rack ,heavy duty racking system, he can't help taking risks when he makes a move. Shi Qing was secretly pleased: "The more eager you are to win, the more likely you will be defeated by me." More than ten strokes in the past, as expected, Bai Wanjian even encountered a dangerous move, his heart a Rin, immediately closed the mind, to strange and take the right path, change to rush to attack for the first, at this point, the two people are really a well-matched fight, too close to call. Shi Putian watched the two men fight, although he did not know the reason, but he could see it. Shi Qing and Bai Wanjian also fought so hard that they forgot their love affair. After more than two hundred strokes, Bai Wanjian felt at ease. He felt that today's fight was really a great pleasure in his life. He had already forgotten the shame of being controlled by Min Rou's sword. Shi Qing is also deeply pleased to meet this strong enemy. Two people naturally give birth to the feeling of sympathy, hostility gradually, and the heart of the competition is more and more prosperous, each show their unique skills, to see how the other side disassembled. At the beginning of the fight, there was a clanging sound in the hall, but at this time there was only the clanging sound of the two swords. At the end of the fight, Bai Wanjian made a move of "dim fragrance and thin shadow", and the blade of the sword slanted over. Shi Qing gave a low praise: "Good swordsmanship!" As soon as the vertical sword stands, the two swords intersect. Both of them used their inner strength in this move, and with a clap, the green steel sword in Shi Qing's hand was broken. As soon as the sword in his hand was broken, a sword from his left was handed up. Shi Qing took it with his left hand and made a move to "have it both ways." The long sword drew an arc in front of him from left to right to prevent the other side from continuing to attack. Bai Wanjian stepped back and said, "This is because Shi Zhuangzhu's sword is inferior in quality. It is not because he won or lost in the sword.". If Lord Shizhuang had a black sword in his hand, how could he break it? It's the brother's fault. "As soon as he said this, his face suddenly changed, and he realized that it was Min Rou who stood on the left of Shi Qing and handed him the sword. The eighteen younger martial brothers of this school were lying all over the ground.". It turned out that when Bai Wanjian was concentrating on fighting with Shi Qing, Min Rou had already stabbed the eighteen disciples of the Snow Mountain Sect to the ground one by one. Everyone was slightly wounded by the sword, but Min Rou's internal force passed from the tip of the sword to the acupoint, which made them unable to move any more after being hit by the sword. This is one of Min Rou's best swordsmanship. She was benevolent and did not want to kill the enemy, so she was ingenious and melted Shangqingguan's acupoint method into swordsmanship. Although the eighteen disciples of the Snow Mountain Sect were hit by the sword, they were actually hit by her internal force, but her internal force was not up to the best level. Otherwise, if the tip of the sword touched the opponent's acupoint, it would be able to defeat the enemy without injuring his flesh. As soon as Min Rou handed her husband a long sword in her hand, she picked up a long sword from a disciple of the Snow Mountain Sect from the ground, held it in her hand, and stood three steps behind her husband's left side, so that she could grab the attack at any time. Bai Wanjian's heart sank and he thought, "Shi Qing and I can only fight to a draw. If Mrs. Shi joins the battle group again, what else can we fight?" He said sadly, "It's a pity that Elder Martial Brother Feng is not here. Otherwise, if Feng and Bai join hands, they can have a fight with the virtuous couple.". What else is there to say now that the defeat has been achieved? "Yes," said Shi Qing,radio shuttle racking, "I'll meet the Wind and Fire Dragon in the future.." Before he had finished a sentence, he remembered that Feng Wanli's arm had been beheaded by his master for the sake of his son Shi Zhongyu. Even if he met him in the future, he would not be able to compete with the sword. He immediately stopped and stopped talking. His face was deeply ashamed. He was not happy that the couple had joined hands to defeat the nineteen disciples of the Snow Mountain Sect. omracking.com

Guo Ding gritted his teeth, turned around and grabbed her knife. He did not take her knife, but his other hand was clasped behind her left neck like lightning. Ding Linglin's eyes suddenly straightened and she fell down. There was no one on all sides, and the frost on the roof was as white as silver. Ding Linglin's call unexpectedly did not alarm the Jade Xiao Taoist. Guo Ding has picked up Ling Lin, he is anxious to go back to see Ye Kai's injury, has ignored the suspicion of men and women. But there was no one in the room. There are no living people. Han Zhen, who had been sleeping in a coma, had been nailed to her bed by a long sword. The blood on the ground had congealed, and it was Ye Kai's blood. There was also blood on the corner of the table, which was also Ye Kai's blood. But Ye Kai has disappeared, and so has Cui Yuzhen. Whose sword is it? Who did this to you? Why do you want to kill a man who is half dead? Where did Ye Kai go? Could it be that Cui Yuzhen had brought him back to Wang Xiao Taoist? In any case, he is doomed. The room is small, but it is very clean. There was a small wooden cabinet in the corner of the room, which was locked, and a bronze mirror was placed on the dressing table beside it. The cold wind made the window paper rustle, the curtain hung on the door, and the fragrance of medicine came from outside the door. Ye Kai is not dead. He had woken up,Narrow aisle rack, and when he woke up, he found himself in such a place. Then he found himself lying naked on the bed, covered with three thick quilts. The wound on his chest had been bound up with a white cloth, and it was well bound up. Who bandaged him? What the hell is this place? He wanted to sit up, but there seemed to be a knife in his chest, and when he moved, it hurt so much that his whole body seemed to tear. He wanted to shout,warehouse rack manufacturer, but by this time the curtain had been lifted and a man had come in slowly with a bowl of medicine. Cui Yuzhen. She had taken off her Taoist robe and was dressed in a blue cloth dress. Her eyebrows were lightly swept and she did not apply makeup, but there was a deep sadness between her eyebrows. Seeing that Ye Kai had woken up, her eyebrows had opened. How did I get here? Ye Kai asked this sentence, immediately found that this is nonsense, of course, Cui Yuzhen will save him here. Cui Yuzhen had come over and gently put the medicine bowl on the small table beside the bed. Her every movement looked so gentle that she was no longer the female Taoist who twisted her waist with the sound of the flute. Ye Kai looked at her, suddenly had a very safe feeling, the heart has also settled down. But he couldn't help asking, "What is this place?" Cui Yuzhen hung his head and blew the medicine gently. It took him a long time to answer: "It's someone else's home." "Whose house is it?" "He is a businessman in the tea business." "Do you know him?" Asked Ye Kai. Cui Yuzhen did not answer this, but said softly, "You are badly hurt. I am afraid that the Taoist Yuxiao will come, so I have to take you away quickly." She is a very careful woman, Warehouse storage racks ,Cantilever Storage rack, very thoughtful. If Ye Kai had stayed in that room, he might have been nailed to the bed by a long sword. "But the first time I went to Chang'an," said Cui Wangzhen, "I didn't know anyone. It was just dawn. I really didn't know where I should take you." "So you broke into this man's house?" Asked Ye Kai. Cui Yuzhen nodded and said, "This is a very ordinary small family. Absolutely no one thought you would be here." "Of course you don't recognize the master here," said Ye Kai. Cui Yuzhen had to admit: "I don't know." She said she didn't know anyone in Chang'an. "Where are they now?" Asked Ye Kai. Cui Yuzhen hesitated, and after a long time, he said softly, "I've killed him." She hung her head and did not dare to look at Ye Kai. She was afraid that Ye would scold her at the meeting. But Ye Kai didn't even say a word. He is not the kind of sanctimonious Taoist gentleman, he knows that if it were not for Cui Yuzhen, he would not know who died now. There are a lot of people who want to kill him in Chang'an. A half-baked woman, risking her life to save him and taking care of him wholeheartedly, killed him for his safety. How can he have the heart to scold her? How can he scold her. Cui Yuzhen said, "When I broke in, there were two people sleeping on the bed. I thought they were a couple.". "Ye Kai finally couldn't help asking," Aren't they? " Cui Yuzhen shook her head and said, "The woman is more than thirty years old, but the man is only seventeen or eighteen at most. I forced them to ask, and the child told the truth." It turned out that the husband had gone to other places to buy tea, and the wife seduced the apprentice who worked as a handyman in their home. Cui Yuzhen's face seemed a little red, then said: "These two people betrayed their husband, one betrayed his master, so I will kill them, I.." I just hope you don't think I'm a ruthless woman. Ye Kai looked at her, and suddenly there was an indescribable taste in his heart. She had done these things for him and risked so much for him, but she did not want him to thank her, let alone repay her. Her only hope was that he would not think less of her. His opinion is so important to her. Ye Kai couldn't help sighing and said softly, "I hope you understand one thing, too." "What is it?" Ye Kai said, "If anyone thinks you are doing something wrong and that you are a ruthless woman, that person must be a hypocrite and a big bastard." He smiled and said, "I hope you believe me. I'm not such a bastard." Cui Yuzhen smiled, and when she smiled, it was as if winter had passed and spring had arrived. The medicine is ready for you. Will you drink it? She picked up Ye Kai and, like a mother coaxing a child, fed him the bowl of medicine in one mouthful. This is my own medicine, I dare not go to the doctor, I am afraid that others will find out your whereabouts from the doctor's mouth. She is really a very careful woman, and she is very thoughtful at every point. Ye Kai looked at her, filled with warmth and gratitude,Narrow aisle rack, and said with a smile, "It's really luck that I met you. You seem to be able to imagine everything." Cui Yuzhen hesitated and suddenly said, "But I still can't figure out why she wanted to kill you." Ye Kai's smile faded. omracking.com

When Mu Tianchen saw Wei Cuisine dragging Su Man down, he took the initiative to say that he wanted to help her. Wei Cuisine was elated, but when he felt the gloomy eyes of Yin Yueyue, he quickly shook his head and refused. Now seeing the two male nuns of Dan Daozong quickening their pace, the disciples of Xianyue Zong were anxious, but because the three female nuns in the team were dragging their feet, they could only continue their leisurely journey. As they got closer and closer to the water source, the surrounding space became narrower and the air became more and more humid, and soon a curtain of waterfalls appeared in front of them. The waterfall poured down from the Wanzhang cliff, the sound was like thunder, and the waves splashed in all directions. Not far from the waterfall, between the two cliffs, there was a cave, in which two monks of Dan Daozong were now. Everyone's eyes lit up and they went to the cave. Mu Daoyou, there is light coming from the cave. I don't know if there are other exits. Younger Martial Brother Zhang and I are going to go deep to have a look. As he spoke, the monk, surnamed Wan, took out a message from his storage bag and handed it to Mu Tianchen, saying, "If there is any news, I will send you a message." The two monsters can't tell the difference for the time being, and they don't know when to fight. Now that they have found a possible exit, they naturally want to explore it. Hearing what the monk surnamed Wan said,Industrial pallet rack, Mu Tianchen did not say much, but reached out to take the messenger and told the other party to be careful. After Friar Wan and Friar Zhang left, Mu Tianchen took out a set of defensive formations and arranged them at the entrance of the cave. On the other side, one practices Qi Dzogchen and the other practices Qi Jiuyuan. They are the best in the Qi training period. Unlike their team, the level of cultivation is uneven. If they don't repair it at this time, some people are afraid that they will lie on the ground directly. By the time Mu Tianchen finished turning around, the disciples were already sitting cross-legged on the ground, meditating and breathing. After walking all day,Pallet rack upright, I was really tired and my whole body was sore. Only meditation and practice could relieve fatigue. Mu Tianchen was the same. He was just about to sit cross-legged on the ground, but when his eyes swept over Su Man, he could not help moving. At this moment, Su Man's eyes were closed tightly, and the pure Reiki around her was moving closer to her. The purity of the Reiki looked purer than the Reiki absorbed by his variant spirit root. It was really strange. Although he was confused, Mu Tianchen turned his feet and came to sit down beside Su Man. Then he closed his eyes and slowly ran the method. I don't know if it was Mu Tianchen's illusion, but he felt that when he meditated beside Suman, the aura he absorbed seemed to be purer than before. The author has something to say: chishans, the landmine of the big boss, thank you for your message support, love you ( 'ε`) 、032 When I opened my eyes from the practice, I saw Mu Tianchen sitting beside Su Man. Thinking of the recent rumors in the school, everyone's eyes flashed a look of clarity. Only Yin Yueqi's eyes were red. Her hands were clenched tightly, and her nails sank into the flesh without knowing it. Yin Yueyue's line of sight is too strong, Su Man can naturally feel, but she did not care too much, Pallet rack beams ,heavy duty warehouse rack, she and Yin Yueyue's quarrel has been formed, no matter how she can not reverse, can only secretly pay more attention to some. Although the aura in the secret realm is very strong, they enter the secret realm to find the treasure of genius, not to practice here. So after a day of repair, Mu Tianchen stood up. He first looked outside the cave, and then looked into the depths of the cave. Just as Mu Tianchen hesitated whether to go out of the cave or to go deep into the cave, the jade amulet on his body suddenly rang. After entering the secret realm, people outside the secret realm and people inside the secret realm can not contact each other through the messenger because of the prohibition. And there is a certain distance limit for communication with the messenger. You don't have to think that the messenger was sent by the monk with the surname of ten thousand. When you open it, the voice of the monk with the surname of ten thousand came from inside. "Mu Daoyou, there is an exit at the end of the passage." There was an unconcealed excitement in the voice of the monk surnamed Wan. "I saw twelve thousand years of blood Ganoderma lucidum here." Blood Ganoderma lucidum is not very scarce in the realm of cultivating immortals, but it is rare for thousands of years. Monks make alchemy. The higher the year of Lingcao, the higher the success rate and the rate of becoming an elixir, and it is easier to refine the best elixir. This kind of herb, Zongmen is very interested in, how can this person tell himself such a good thing?! Just as Mu Tianchen was wondering, he heard the monk Wan continue to say, "But there are three eight-eyed poisonous spiders waiting beside these thousand-year-old blood Ganoderma lucidum. Younger Martial Brother Zhang and I can't deal with them.". If you come here, we will divide the ten thousand-year-old Ganoderma lucidum plants according to their heads, and the remaining two plants will belong to you and me. What do you think? The poisonous spider has eight eyes, and the silk it spits out is highly poisonous. Once it is entangled, if it can not get away in time, it is easy to suffocate and die. Although Mu Tianchen was moved, he still looked at the crowd and asked, "What do you think?" Everyone looked at me and I looked at you, and finally said in unison, "Listen to Elder Martial Brother Mu." Although they are very interested in the thousand-year-old Ganoderma lucidum, the eight-eyed poisonous spider is very difficult to deal with. When these people go, they mostly rely on two monks who practice Qi Dzogchen, so the decision is naturally given to the leader. Hearing the crowd's answer, Mu Tianchen said, "Then let's set out." With these words, Mu Tianchen waved his hand and led the crowd to the depths of the cave. The cave is very damp, surrounded by smooth stone walls, and from time to time there is the sound of falling water drops, which makes the cave more quiet. Because just added physical strength, everyone's condition is very good, and then think of not far away there are more than a dozen thousand-year-old blood Ganoderma lucidum waiting for their own, is full of rush, one by one walking with wind, the speed is much faster than before. Yin Yueyue closely followed behind Mu Tianchen, before tired to walk, although want to be closer to Mu Tianchen, but powerless, but now can do so. But Yin Yueyue is very interesting, she knows that when Mu Tianchen walks, all her energy is in observing the surrounding environment, simply can not distinguish between the mind and chat with them, so although Yin Yueyue followed Mu Tianchen half a step behind, but did not open his mouth to disturb Mu Tiancheng. Her eyes fell on Mu Tianchen from time to time,Steel racking system, and the man in front of her stood tall and straight, like a green bamboo, and her heart beat like a drum. omracking.com

Original title: Can wearing masks for a long time induce lung cancer? Bullshit! This article is all about the purchase and wearing of masks. Recently, the Shanghai Anti-rumor Platform received a message from netizens, hoping to verify whether the statement that "lung nodules increase significantly after wearing masks for a long time" is correct. According to online reports, some people attributed the harm of masks to the melt-blown cloth in the middle layer of masks, pointing out that melt-blown cloth is a petroleum product, "micro-particles enter the lungs through the respiratory tract", so it is harmful. Is this true? If wearing masks for a long time is so harmful, what about doctors and other people who need to wear masks for a long time? Mask melt-blown nonwovens do not release "fine particles" Zhou Yiming, an associate professor of general surgery at Huashan Hospital affiliated to Fudan University, said the online news was unreliable. He pointed out that in addition to blocking the spread of COVID-19, masks can also prevent various respiratory diseases caused by inhaling haze, but masks are not effective in blocking tobacco smoke, the biggest risk factor for lung cancer. The main side effects of wearing masks for a long time are chronic hypoxia and skin problems caused by hot and humid weather. This is why disease control experts remind the public to wear masks with different levels of protection on different occasions, because among all kinds of masks, masks with higher levels of protection, such as N95, have greater respiratory resistance and are not suitable for long-term wear. He also warned that the most effective way to prevent lung cancer is to avoid smoking, breathing second-hand smoke and paying attention to healthy diet. As for the rumor that "melt-blown cloth will release micro-particles", the Shanghai anti-rumor platform also consulted a number of chemical experts, saying that the statement is nonsense. Relevant people pointed out that melt-blown cloth is the core material of masks, and it does use petrochemical polypropylene as the main raw material, but it will not release particles. According to the logic of online messaging,KN95 Mask with Fast Shipping, it means that all plastic products are volatile. Plastic is a polymer structure, normally molecules are bonded together, and it is impossible to "degrade" or "release" small particles. From the perspective of application scenarios, plastic products and related raw materials are widely used worldwide, including medical, food and so on, and the application is becoming more and more extensive. If these products are harmful to the human body, how can these applications be obtained? At the same time, qualified listed plastic products and related raw materials need to undergo professional testing to meet the national and industry standards, and there is no risk of online transmission. These misunderstandings related to masks should also be clarified. The Shanghai Anti-rumor Platform also found that questions such as "what kind of masks to choose on different occasions", "whether masks disinfected with ethylene oxide will also carry poison" and "how to choose qualified masks" have been repeatedly mentioned. In fact, KN95 Face Mask ,Full Body Disposable Coverall, they all have official answers. How to choose masks for different occasions? Recently, the weather in Shanghai has become hot, and many citizens say that they can't wear masks. In this regard, Wu Huanyu, deputy director of the city CDC, reminded the public that they should still wear masks when they go out, because wearing masks is an effective way to block respiratory droplet transmission. When wearing a mask, the public should pay attention to the complete coverage of the mouth and nose when wearing a mask. However, the type of mask can be adjusted according to the scene: If you go to outdoor places such as parks, you can wear disposable surgical mask. If you go to shopping malls, supermarkets, offices and other indoor places, you can wear particulate matter protective masks, that is, KN95/N95 mask. If you need to go to the hospital for medical treatment, it is recommended to wear KN95/N95 and above particulate protective masks or medical protective masks. Expand the full text Masks disinfected with ethylene oxide are poisonous? This is a rumor that has been cleared up many times. Zhou Yiming said that ethylene oxide is a common disinfectant and is indeed toxic, but it is not scientific to talk about toxicity without dosage. The residual amount of ethylene oxide in masks produced according to the standard process will not endanger health. For the public, it is more important to choose qualified masks. Wearing a mask can blow out the lighter, but the mask is not qualified? For the selection of qualified masks, there are also some folk "secret recipes" circulating on the Internet, including "wearing a mask can blow out the lighter, indicating that the quality of the mask is not good; can not blow out, indicating that the quality of the mask is reliable". Shanghai CDC has made it clear that this evaluation method is not comprehensive and reliable. Shanghai CDC said that wearing a mask to blow a lighter can only qualitatively reflect the exhalation resistance of the mask, and can not reflect the key technical indicators of the mask-filtering efficiency. For the public, two points should be paid attention to when choosing masks: One is to inquire about the registration number of the mask. In China, medical masks are managed as medical devices and must be filed with the drug supervision and administration department. Usually, the public can see the registration certificate number on the mask packaging, and then inquire through the National Medical Products Administration official website https://www.nmpa.gov.cn/. If it can be found, it means that the product has been registered and filed, and the product is more credible. It should be noted that particulate protective masks (including common KN95 masks or N95 mask) are not regulated as medical devices, so they cannot be queried through the above website. However, the Market Supervision and Administration Bureau will conduct spot checks and publicize the unqualified products. The second is to check the implementation standard number of the mask. Each mask has its corresponding product standard. For example, for disposable medical masks, the corresponding standard is "YY/T 0969 Disposable Medical Masks"; The standard corresponding to the surgical mask is "YY 0469 surgical mask", and the standard corresponding to the KN95 respirator or N95 mask is "GB 2626 Respiratory Protection Self-priming Filter Particulate Respirator" or "American NIOSH Certification" or "European EN149"; The corresponding standard for medical protective masks is "GB 19083 Technical Requirements for Medical Protective Masks" or "NIOSH Certification".

Original title: [Share] The medical masks and protective suit standards you need are here! Get a sneak peek! www.dedayc.com Extraction code: n7s1 Recently, the epidemic is still going on, and when you protect yourself, your enthusiasm for learning is not diminished. Mask, protective suit, disinfection, sterilization. Let's learn some relevant knowledge together today. Medical protective suit refers to the protective clothing used by medical staff (doctors, nurses, public health personnel, cleaning personnel, etc.) And people entering specific medical and health areas (such as patients, hospital visitors, people entering infected areas, etc.). Its function is to isolate germs, harmful superfine dust, acid and alkaline solutions, electromagnetic radiation, etc., to ensure the safety of personnel and keep the environment clean. More than 100 years ago, in order to prevent microorganisms from invading sterile operating rooms and protect patients from bacterial infections carried by medical staff, hospitals began to use special surgical protective suit. Expand the full text In 1952, the William C. Beck pointed out that the material of surgical gowns should be able to prevent the entry of liquids. In the past, surgical gowns were resistant to bacterial penetration when dry, but not to bacterial invasion when wet. During World War II, the U.S. Army developed a high-density woven fabric treated with fluorocarbons and benzene compounds to enhance its waterproof performance, and civilian hospitals began to use these fabrics as medical protective suit fabrics after the war. Since the 1980s, with the in-depth understanding of blood-borne pathogens such as HIV, HBV and HCV, people have paid more and more attention to the risk that medical staff may be infected in the process of treating patients, so countries began to focus on the development of medical protective suit,Full Body Disposable Coverall, making the protective clothing industry flourish. Especially in the course of the outbreak of SARS (atypical pneumonia) in 2003, there were many cases of medical staff being infected, which made people realize the importance of self-protection. Medical protective suit includes all types of clothing specifically worn in the medical environment, so there are many ways to classify them. 1. According to the purpose According to the purpose and application, it can be divided into daily work clothes, surgical gowns, isolation gowns and protective suit. Daily work clothes refer to the white coats worn by medical staff in their daily work, also known as white coats. Surgical gown refers to a specially designed garment worn in the operating room. Isolation clothing refers to the clothing worn by medical staff in contact with patients, family visits to patients and other occasions. Protective suit refers to the clothing worn by personnel in special areas such as medical first aid, infectious disease areas and electromagnetic radiation areas. 2. According to the service life According to the service life, medical protective suit can be divided into disposable protective suit and reusable protective suit. Domestic disposable medical surgical gowns comply with the industry standard YY/T 0506-2016 Surgical Drapes,KN95 Face Mask with Five Layers, Surgical Gowns and Clean Clothes for Patients, Medical Staff and Instruments issued by the State Food and Drug Administration and implemented on January 1, 2017. The medical disposable protective suit shall comply with the technical requirements for medical disposable protective suit specified by the Standardization Administration of the People's Republic of China and implemented from March 1, 2010: GB19082-2009. Disposable protective suit are discarded immediately after use without disinfection and washing, which are convenient to use and can avoid cross infection. However, disposable materials degrade slowly and are easy to cause environmental pollution. Usually, surgical gowns and isolation gowns with high protective requirements are of this type. The reusable type requires washing, high temperature disinfection and other measures after use. Generally, the comfort of the material is better, but the protective performance is usually poor. The washing and disinfection process will also increase the cost of manpower and water resources. This type is usually used for daily work clothes (white coats) with less protective requirements. 3. According to the material According to the different processing technology of materials, medical protective suit can be divided into woven and non-woven protective suit. Woven materials are mainly used to process reusable medical protective suit, including traditional woven fabrics, high-density fabrics, coated fabrics and laminated fabrics. Traditional woven fabrics are mainly made of blended yarns of cotton fibers or synthetic fibers such as polyester and cotton, which have good comfort and are mainly used for daily work clothes (white coats). High density fabric is made of high count cotton yarn or other superfine synthetic fiber filament. The yarn gap is very small. Due to the capillary action of the fiber, it has moisture permeability. After being treated by fluorocarbon, silicone and other waterproof agents, it has certain liquid penetration resistance. It is mainly used for surgical gown materials requiring better waterproof effect. Coated and laminated fabrics are used to enhance the barrier properties of materials used in harsh protective suit environments. The coated fabric is subjected to coating processing, the surface of the coated fabric is sealed by a coating agent, and the coated fabric has impermeability; and the hydrophilic groups in the coating or a microporous structure formed by a special method ensure the moisture permeability of the fabric. Laminated fabric is a kind of fabric which is laminated with a special film (such as microporous film, polyurethane moisture permeable film, Medical Disposable Coverall ,Antivirus Disposable Mask with CE Certificate, etc.), such as PTFE super waterproof and moisture permeable composite fabric. Because the aperture of the micropores of the fabric main body membrane is far smaller than the diameter of a water drop, the permeation of blood, body fluid and the like can be prevented, the porosity of the micropores is high, the aperture is larger than the diameter of water vapor molecules, and the water vapor molecules can freely pass through, so that the moisture permeability is good. Nonwoven protective suit materials are basically disposable, such as spunbond nonwovens, spunlaced nonwovens, SMS (spunbond-meltblown-spunbond) composite nonwovens and flash evaporation nonwovens. In general, nonwoven protective suit have better protective properties than machine-made materials. Performance requirements In addition to the specifications and safety requirements of the material itself, the performance of medical protective suit mainly includes protection, comfort, physical and mechanical property, etc. 1. Protection Protection is the most important performance requirement of medical protective suit, mainly including liquid barrier, microbial barrier and particulate matter barrier. Liquid barrier means that the medical protective suit should be able to prevent the penetration of water, blood, alcohol and other liquids, with more than four levels of hydrophobicity, so as not to contaminate clothes and human body. Prevent the patient's blood, body fluids and other secretions from transmitting the virus to the medical staff during the operation. Microbial barrier properties include the barrier to bacteria and viruses. The barrier to bacteria is mainly to prevent contact transmission (and reverse transmission) from medical staff to the patient's surgical wound during the operation. The barrier to viruses is mainly to prevent medical staff from contacting patients'blood and body fluids, which carry viruses causing cross infection between doctors and patients. Particulate matter barrier refers to the prevention of airborne viruses from being inhaled in the form of aerosols or attached to the skin surface and absorbed by the human body. 2. Comfortable Comfort includes breathability, water vapor penetration, drape, mass, surface thickness, electrostatic properties, color, light reflection, odor, and skin sensitization. In order to enhance the protective effect, protective suit fabrics are usually laminated or laminated, resulting in heavy and poor air permeability and moisture permeability, which is not conducive to perspiration and heat discharge for long-term wear. Antistatic requirements are to prevent static electricity in the operating room from causing the surgical gown to absorb a large amount of dust and bacteria, which is harmful to the patient's wound, and to prevent the sparks generated by static electricity from detonating volatile gases in the operating room and affecting the accuracy of precision instruments. 3. Physical mechanical property Physical mechanical property mainly refers to the ability of medical protective suit materials to resist tearing, puncture and wear. Avoid tearing and puncturing to provide a channel for the spread of bacteria and viruses, and wear resistance can prevent the flocculation to provide a place for the reproduction of bacteria and viruses. 4. Other properties In addition to the properties listed above, medical protective suit should also have the properties of disinfection resistance, good color fastness to washing, shrinkage resistance, non-combustion-supporting, non-toxic and non-irritating, and harmless to skin. Special medical protective suit. 1. Chemical protective suit Chemical protective suit is a kind of protective clothing to protect oneself from dangerous chemicals or corrosive substances when dealing with dangerous medical chemicals. Chemical protective suit requires not only chemical resistance of clothing materials, but also more stringent requirements for sealing and seam structure of clothing. 2. Electromagnetic radiation protective suit Electromagnetic radiation protective suit is a kind of protective clothing which can shield electromagnetic waves in the range of 100 kHz to 300 GHz by implanting very fine conductive fibers in fabric materials, so that protective suit does not produce static electricity. It is mainly used for operators of electronic medical equipment systems in hospitals. 3. Nuclear and radiographic protective suit. It is used in nuclear radiation environment (small dose and large range of ionizing radiation, mainly alpha and beta rays) to prevent radioactive aerosol and dust from harming human body. It has the functions of protecting radioactive aerosols, more than 150 kinds of toxic and corrosive gases, liquids and solids, potential radioactive particles and liquids from invading the body, and 100% blocking dry particles above 0.2 μm. Recently, many group friends have been looking for standards with our teachers, especially sorting out the relevant information about masks and protective suit. Please download and learn by yourself. www.dedayc.com Extraction code: n7s1 Hubei needs 100000 sets of protective suit a day, with a gap of tens of thousands of sets. Faced with the safety of medical staff, China has taken various measures to ensure supply, including temporary emergency measures. First, enterprises resume production and work. Second, the state directly allocates materials. Third, when the medical protective suit is not enough, export medical protective suit can be used. Fourth, strengthen foreign procurement.

Original Title: US Rejects China's KN95 Mask! The export qualification of masks is not up to standard! CE and FDA certification are indispensable Recently, the Food and Drug Administration of the United States launched a new "Emergency-Use-Administration" (EUA), which States that only six countries and regions can accept respirator products that meet the specified performance standards, compared with the previous list issued by the CDC of the United States. Only China is missing from the new table, as follows: This news has caused great concern, because in the previous "Optimizing N95 mask Supply Strategy: Crisis/Alternative Strategy" published by the United States, CDC said that during the shortage of N95 mask, it is necessary to consider suitable alternatives for N95 mask, and when the supply is insufficient, some products are expected to replace N95 mask. The following is a list of relevant national products published by CDC: Expand the full text Australia, Brazil, China, Europe, Japan, South Korea and Mexico are listed, and the acceptable product categories include China's four mask models of KN 100, KP100, KN95 and KP95. But now the United States has temporarily changed its mind, the reasons may be very complicated, but it may have a lot to do with the recent frequent substandard products of medical supplies exported from China. Half of the masks exported to the Netherlands are not up to standard. Several Dutch media reported on March 28 that the Dutch government had recently imported a batch of masks from China,Medical Disposable Coverall, but a large part of them were found to be "unqualified". The masks have been distributed to hospitals, and the Dutch Ministry of Health is recalling them. The total number of masks imported from the Netherlands is 1.3 million, which is used to distribute to medical workers on the front line of COVID-19 epidemic prevention. However, the 600,000 masks that have arrived have been accused of "a large number of substandard problems", including that the masks do not fit the face properly and the filter elements do not effectively block fine particles containing viruses. Spanish test kit is only 30% accurate According to Spanish media reports such as El Pais and El Mundo, the results of a batch of new coronavirus rapid detection kits purchased by Spain from China are not accurate. According to the requirements,KN95 Mask for Epidemic Prevention and Control, the accuracy of the kits should be more than 80%, but this batch of kits is only 30%. The Spanish government said in a statement that the defective kits were not purchased directly by the Spanish government from the Chinese government, but imported from Chinese manufacturers through a domestic supplier. As the incident coincided with Spain's announcement that it would spend 432 million euros to buy medical supplies from China, the incident attracted great attention on Spanish social networks. Products exported overseas should meet local qualification certification. At present, the epidemic situation in foreign countries is getting worse and worse, and there is a huge gap for epidemic prevention supplies. The number of epidemic prevention supplies exported from China is also very large, and it is inevitable that dragons and snakes are mixed. Quality problems are not absolute in some cases, which to some extent include user requirements and experience problems, perhaps only the country's testing standards are different from those of China or the European Union, which leads to such a conclusion, but there is also the possibility that some products do not meet the quality standards. Therefore, the testing and certification qualifications of various regions are particularly important, such as CE certification of the European Union, FDA certification of the United States, CE Certificate KN95 Mask ,Against Bacteria Breathable KN95 Face Mask, etc. Only products with these certifications can be exported to the corresponding countries and regions. America Necessary information (qualification) Bill of lading, packing list, invoice Personal protective mask NIOSH testing certification is required, that is, National Institute for Occupational Safety and Health certification. Medical mask It must be registered with the FDA of the United States. European Union Necessary information (qualification) Bill of lading, packing list, invoice Personal protective mask The EU standard for personal protective masks is EN149. According to the standard, masks are divided into three categories: FFP1/FFP2 and FFP3. All masks exported to the European Union must obtain CE certification. CE certification is a compulsory product safety certification system implemented by the European Union, aiming at ensuring the safety of life and property of the people in EU countries. Medical mask The EU standard for medical masks is EN14683. Products sold in the EU need to issue the EU Free Sale Certificate. With the CE mark and the EU registration required by the relevant directives, Chinese manufacturers do not need the Free Sale Certificate to export to the EU. Japan Necessary information (qualification) Bill of lading, packing list, invoice, manufacturers outside Japan must register manufacturer information with PMDA. Mask packaging requirements The package is printed with the words (Chinese translation: virus blocking) 99%. PFE: 0.1 um particulate filtration efficiency BFE: Bacterial Filtration Rate VFE: Virus Filtering Rate Mask quality standard 1. Medical protective mask : Comply with China's GB 19083-2010 mandatory standards, filtration efficiency ≥ 95% (using non-oily particles test). 2. N95 mask: NIOSH certification, non-oily particulate matter filtration efficiency ≥ 95%. 3. KN95 mask: It meets the mandatory standard of GB 2626 in China, and the filtration efficiency of non-oily particles is ≥ 95%. Korea Necessary information Bill of lading, packing list, invoice, Korean importer's business license. Standard for personal protective mask KF (Korean filter) series is divided into KF80, KF94 and KF99 Implement standard specifications MFDS Notice No. 2015-69 The regulatory threshold for the access of medical devices in Korea is basically classified into Class I, II, III and IV, the License holder is a Korean company, and the Korean consignee needs to Korea Pharma ceutical Traders Association. With the Korean Food and Drug Administration. Import qualification for filing in advance Website: www. Kpta. Or. Kr. Australia Necessary information Bill of lading, packing list, invoice. Must be registered with the TGA in Australia and comply with Standard Specification AS/NZS 1716:2012, which is the Australian and New Zealand standard for respiratory protective devices. TGA is the abbreviation of Therapeutic Goods Administration, which is the supervisory body of therapeutic goods (including drugs, medical devices, genetic technology and blood products) in Australia. Medical devices in Australia are classified into Class I, Is and Im, IIa, IIb and III. The classification of products is almost the same as that of the European Union. If the product has obtained the CE mark, the product category can be classified according to CE. Professional Qualification Certification Helps Mask Export Worldwide At present, the global epidemic is spreading, and masks have become a necessity for human beings. However, when masks go abroad to various countries, they need to have corresponding qualification certification.

Original title: When the Soviet Union dug through the earth, why did it stop digging to 12265 meters? 50 years later, the truth comes to light. Earth It is the mother of human civilization. Since the birth of human beings, the earth has silently provided shelter, water and food under the feet of human beings. Until now, Mankind has a history of three million years. Today, human beings can go to space to land on the moon and go down to a 10,000-meter-deep trench for scientific research, thus realizing the desire of "going up to the sky and down to the sea". But, Even though human technology is very advanced, Knowledge of the Earth beneath our feet is still scarce. During the Cold War between the United States and the Soviet Union in the last century, the two superpowers competed in various fields, including scientific and technological exploration. Among, America To study the secrets of the depths of the earth, Undertook a plan that sounds incredible: Dig through the earth! Soviet Union After learning about it, The same plan was carried out, And in When the United States could not dig to 500 meters, the Soviet Union dug to a depth of more than 10,000 meters. But what makes later generations wonder is why the Soviet Union dug through the earth. Expand the full text 12265 rice Just stop? The truth about the plan did not come to light until 50 years later. Excessive input In fact, the original idea of the Soviet Union to set up this plan is the same as other "arms race" projects, mining drill bit , except that In order to surpass the United States in a certain field and prove the superiority of its own system. Therefore, although we know that a project that simply "digs holes" is likely to have no return. The Soviets decided to try, at least to dig deeper than the Americans. At that time The Soviet Union's excavation plan was chosen The Kola Peninsula, This place Located in the northwestern tip of Russia, most of its area is within the Arctic Circle. But in order to make the technicians feel at ease to stay here and "dig holes", the Soviet Union arranged very generous benefits for the project personnel, each of whom had a villa in the Black Sea Resort, and also delivered a large number of supplies on time. Encouraged by this policy, the progress of the project is indeed very fast, and more than 10,000 meters have been dug in just a few years. Can't see the return But, When the Soviet Union dug more than 10000 meters, the excavation work encountered difficulties: The tunnel here is already a high temperature environment deep in the earth. The drill bit of the drilling rig will burn down in a few minutes. If we continue to dig, the cost will be higher and higher. But what is the actual value of this project? No one can answer. Because The cost of the project is so high that these excellent technicians only need to dig holes. Actually, also It is a waste. After consideration, therefore, The relevant leaders of the Soviet Union stopped the digging project. The Soviet record for digging a hole was only 12265 meters. Mysterious legend After the Soviet Union ended the project, there were many mysterious legends: Some people say that the Soviet Union stopped digging because it heard "voices from hell". This statement has aroused the interest of a large number of people, and they are very curious about what the Soviet Union's project has achieved. Is there really a "hell" in the depths of the earth that modern science does not know? However, according to the former Soviet documents disclosed by Russia 50 years later, The idea of "hell" is just an urban legend. The truth is, Soviet technicians did hear mysterious sounds from the depths of the earth. But it was later found out that It's just the wind from an underground cave somewhere in the tunnel. However, human exploration of the earth will never stop here, and people will inevitably use more advanced technology to explore the earth under their feet in the future. To understand the earth is actually to understand human beings themselves.

Original title: Running 10: Zhou Shen challenges the Olympic champion, contracts the whole period to watch, and the hot search topic breaks tens of millions of seconds! The tenth program of "Running Bar 10" was still filmed in Changji, Xinjiang. At the beginning of the program, the whole staff appeared in Changji Stadium. The powerful singers in the music world, Zhou Shen and Bai Lu appeared in the same frame, wearing a sportswear, a white coat with red sports pants, showing a special style of painting with a sense of CP. They also put out the shape of "white crane shining wings". He looks very handsome in everything. All kinds of flying kicks make all the guests laugh, which is worthy of being the laughing point of the whole program. Where there is Zhou Shen, there will be laughter, which can bring us unexpected surprises every time. This time, unlike previous programs, the running man family will face the challenge of "kicking the hall". That is to say, the flying guests in this program are all here to "smash the field" and fight with the six champions. The first flying guest is weightlifter Lv Xiaojun. The program also took Zhou Shen, white deer, baby as an example. After watching his personal short film, Zhou Shen's face was full of envy. When shaking hands with Lv Xiaojun, the program also gave Zhou Shen the word "seconds". In fact, it's not that Zhou Shen is afraid to meet with athletes, but out of respect. You know, Zhou Shen is the only image spokesman for the Beijing Winter Olympics. Expand the full text In front of the sportsmen, there was no star shelf at all, and his face was full of smiles. Comedian Sha Yi deliberately accosted Lv Xiaojun and pretended to be very familiar with him. Once again, he was a real "iron fool". The second was Xu Mengtao, who had just participated in the skiing ceiling of "Riding the Wind and Breaking the Waves 3" not long ago. Sigong regretted to withdraw from the competition,down the hole bit, which became a difficult feeling in the hearts of many audiences. Her departure caused Cyndi Wang's team to dance again overnight. Unfortunately, she sprained her foot. For Mango TV, without the pistachio Xu Mengtao, it was really a big loss. I never thought that she would be in the same frame with Zhou Shen in Running Man 10. One is the famous pistachio, the other is the little prince. They are bound to put on a good show. The third is the champion of the women's volleyball team, Zhang Changning, who is 1.95 meters tall. Zhou Shen is very cute. He shakes hands with her while jumping. In front of Zhang Changning, Zhou Shen is more like a middle school student. Zhang Changning also deliberately lets Zhou Shen clap hands with himself, but it is not difficult for Zhou Shen to jump and easily touch his opponent's right hand. It can be seen that Zhang Changning is also a die-hard fan of Zhou Shen. Otherwise,overburden drilling systems, he would not only interact with Zhou Shen. The fourth one is Gao Tingyu, a flying man on ice, and the fifth one is Liu Huihong, a good friend of Jay Chou. He reproduces the famous fitness scene and is known as the Godfather of fitness. From a certain point of view, this program should be called "Athletes Special Show". As soon as he came out, he made a big move. The muscles on his body successfully attracted Zhou Shen's attention. Finally, the finale was the good friend of the champions, Xie Na's apprentice and Zhou Shen's good friend Wei Daxun. His style was extremely different. He looked more like the silly son of the landlord's family. Before opening the game, Liu Huihong led the whole team to warm up and danced the popular "calisthenics" again. The background music is also Jay Chou's masterpiece "Compendium of Materia Medica". Zhou Shen has learned it well, and every movement is in place, which is in sharp contrast to other guests. The plot of Zhou Shen and Liu Huihong dancing "aerobics" is enough to be recorded as a famous scene in the Chinese music world. The first game is called'Summit Duel '. The two teams decide their own order of playing. The members with the same serial number will have a one-to-one battle. They will tear up their nametags and decide the size of their nametags by drawing lots. The more they tear up, the more chances they have to win. After listening to the rules of the game, Zhou Shen shouted,' Is there only one game recorded today? ' No one expected that the program group would play so much at the beginning. Sha Yi was the second to appear on the stage. His opponent was Zhang Changning. He was led by the nose from beginning to end. He had no initiative at all. He lost without any suspense. Invisibly, he also created a lot of famous scenes in the circle. Zhou Shen played in the third round against weightlifter Lu Xiaojun. At this time, Zhou Shen's strength was far less than that of the other side, but he had a special Olympic spirit. If you want to challenge, choose the character of the king level. Only when the strong fight against the strong, dth button bits ,dth drill bits, can you rub out different chemical reactions. After the start, Zhou Shen is particularly methodical. He used the legendary'Lion Roaring Skill 'to give the other side a blow first. He pulled the momentum full, and his hands and feet were extremely flexible. But Lv Xiaojun did not play cards according to the routine. He grabbed Zhou Shen's hand and refused to let go. When the other side was not paying attention, his firepower was all open. Netizens also called it "deep stubbornness". In order to help the team win the honor, Zhou Shen used all his strength and was thrown one after another, which made people feel very distressed. Although he lost to the other side, it was still glorious to lose. As long as he worked hard, after all, the other side was an athlete. In the end, the brother team lost to the champion team with a score of one to five. The second round of the game is called'Fast Meteor '. The two teams take turns to send people to challenge. Members choose the distance to challenge, press the button, and the ball begins to fall. Members need to receive the ball before it falls to the ground. The challenge is successful. The test is the speed of the guests. Each person has two chances to challenge. It has to be said that the program group is so good at playing that they try their best to torment the guests. Zhou Shen, as usual, had a special group soul. He was the first to represent his brother team. He chose to challenge the distance of 8 meters. After starting, he was as fast as lightning and successfully caught the volleyball. Because he was too serious, he was also hit in the throat. It can be called "one ball seals the throat". But Zhou Shen did not complain at all. He always sent out the positive energy of his idol and refreshed the previous cognition of netizens. In the second round, the difficulty increased and the challenge was 9.1 meters. As expected, a kneeling slip, like a rocket, caught the ball steadily and won the applause of the whole team. He proved himself with his strength. Interestingly, when it was Zhang Changning's turn to challenge, Zhou Shen compared her arm length with her leg length, showing the most adorable height difference, which made many audiences laugh. In addition to Sha Yi, the brother team played very well and successfully pulled back a game. In the third round of the game, the members of the two teams were leggings, six people and seven groups. They needed to complete the forward roll, paper cup pass, cross the high ground waist pole, jump rope, a total of five checkpoints. Finally, the team with the shortest time won, testing the tacit understanding of the members. After listening to the rules, Zhou Shen reappeared the classic expression package. In the process, Zhou Shen contracted all the jokes. I believe that many audiences, like me, pay attention to Zhou Shen all the way. Any link is completed perfectly. When the paper cup is passed, the singer's strong vital capacity is brought into full play. The paper cup is passed without hands. The lower waist passes easily. Finally, under the leadership of Zhou Shen, he completed the challenge in 4 minutes and 39 seconds. When it was the champion team's turn, the brother team kept making trouble and lost successively when they went down to cross the pole. In this regard, Zhou Shen's online singing of "Lonely Brave Man" "Love You don't Kneel" once again filled the comedy effect of this program. All the audience in the bullet screen shouted "I haven't heard enough". The final competition was a comprehensive endurance race of marbles. To put it bluntly, let the marbles compete. The marble Zhou Shen got was'Dalmatian ', and the white deer got'Little Jelly', and Sha Yi got'Desert '. Li Chen was the first in the first round. Zhou Shen's'Dalmatian' played in the second round. He felt that Zhou Shen was more excited than he was to participate in the competition. He shouted'Come on Dalmatians' all the way, but unfortunately none of them rushed into the finish line. Finally, the champion team'Win-win 'won the victory of this issue. The audience was very satisfied with the result. After all, This period want to convey is professional ability and sportsmanship. After the broadcast, ZhouShen as always was pushed on the micro Bo hot search, Hot words'Running man vs world champion'Reading volume until today, Reached 32.49 million.
