Different people have different physiques. As said in " Pony Crossing the River ",
Pony ran over and asked, "Uncle Niu, please tell me, can I wading through this river?" Lao Niu said, "The water is very shallow, I just don't have any calves, so I can wading through it."
After hearing Lao Niu's words, the pony immediately ran to the river and prepared to wading through it. Suddenly, an squirrel jumped from the tree, stopped him and shouted, "Pony, don't cross the river, don't cross the river, the river water will drown you!" The pony asked in surprise, "Is the water very deep?" The squirrel said seriously, "It's so deep! Yesterday, one of my friends fell into this river and drowned!"
carefully evaluated the condition of yourself and your family. Don't think that you are not serious just because you saw some netizens saying that they are not serious about the new crown. Because people with serious consequences may not be online at all.
After all, the dead will not accept interviews.
Dead people will not leave messages here.

Winter vacation is coming, and we are about to usher in the first Spring Festival after the relaxation. Many places have put forward the warm slogan of welcoming home for the New Year, and many people also hope that this year's Spring Festival travel rush will be lively and the New Year will be lively. But I still hope that everyone can consider traveling off-peak. After
is released, the first wave of the epidemic will surely come. The speed of arrival is positively correlated with the local flow intensity; the harm of arrival is related to the proportion of local elderly people and local medical conditions.
Large-scale population mobility during the Spring Festival will inevitably accelerate the spread. If everyone is encouraged to return to their hometowns to visit relatives during the Spring Festival regardless of circumstances, it will inevitably aggravate the impact of the epidemic on the countryside and increase the risk of infection among the elderly in rural areas. However, the elderly in rural areas have no voice. They don’t know how to write short essays if they don’t go to , Weibo, and , so they can only let the Internet emotional venters carnival. They are the poorest and most vulnerable bottom class in China, and can only endure and disappear silently in the impact, no one cares about it. This is the Chinese version of the "Marriage Song of the Countryside".

In a cohort data based on the COVID-19 epidemic published by the journal Nature Medicine on November 10, 443,588 people were infected with the COVID-19 outbreak and 40,947 people were infected with the COVID-19 outbreak twice or more. This means that nearly 10% of people have experienced repeated infections.
Among the repeated infections, 92.8% of people have been infected twice, 6.3% have been infected three times, and 0.9% have been infected four times or five times. In other words, in less than three years of the COVID-19 pandemic, some people have been repeatedly infected as many as 5 times. When
is released, I remind you again: infection does not mean that immunity improves, but will only make the body worse. Therefore, after the release, we must still try our best to avoid infection and reduce infection.
I wish everyone can spend a peaceful Spring Festival in good health and peace!
