Why is the hottest weather epidemic still not fully open?

The reasons why the epidemic is not in the hottest weather are as follows:

1, from the experience of China, 1-2 months after the opening of the epidemic will lead to the peak of infection, and the number of infected people will gradually increase, with a small number of uninfected people.

2. Considering the influence on children's learning, especially the senior high school entrance examination and college entrance examination, and the effect of online classes is definitely not as good as that of schools, some influences are irreparable.

3, speed up the infection, improve the progress of infection and save a lot of money.
