Diagnosis of high-speed train conductor from Chengdu to Shanghai. How can everyone on the train accurately prevent and control isolation? I suggest that we can check every car and then isolate the people who have checked. How do we people deal with the epidemic? Since the emergence of the new crown pneumonia epidemic, China has accumulated rich experience in preventing and controlling the epidemic. Judging from the situation of epidemic prevention and control at home and abroad, China's prevention and control measures are very effective. Therefore, when the epidemic appears in front of us, we must cooperate with the prevention and control measures of the government and the local epidemic prevention and control headquarters. Don't panic and obey the epidemic prevention regulations. Pay attention to epidemic information and do a good job of self-protection. Don't go to high-risk areas and don't gather. Wear a mask and wash your hands frequently. More ventilation and frequent disinfection. No rumors, no rumors. If you have fever symptoms, you should go to a regular medical unit and try not to take public transportation.

Ordinary people have done what they can and should do for two years, so as long as they insist on doing what they can and should do now, they have probably done well enough. I don't think ordinary people can do anything anymore. In my opinion, as long as we ordinary people don't do things that are forbidden by national laws, we have probably done well enough. There is no need to do more unnecessary things. It's not very interesting to add drama to yourself. Apart from bringing inconvenience to our lives, it will not be good for the country's epidemic prevention. Isn't this code on the mobile phone enough now? It's almost 50 kilometers away from home, even that "code" is not enough, and there are still 48 hours (7 days) of nucleic acid testing. You see, everyone in the street wears a mask and can't wait to wash their hands when they get home. Such an honest man has really done his best. So, now my mind is very calm. We ordinary people have done what we can and should do, so we don't think about anything else.
