Why don't foreign countries close their doors when the epidemic is so serious?

In fact, countries (including China) did not completely close their doors even at the worst of the epidemic, but only strengthened entry-exit inspection and quarantine.

The "wartime state" issued in response to public health events is quite different from the "wartime state" stipulated by law, and it is more about showing determination to the outside world, which has aroused everyone's concern conceptually. It shows that epidemic prevention has entered a critical period, emphasizing the urgency of current work, focusing on the overall situation when it comes to the interests of all units and individuals, and focusing on epidemic prevention and control itself in policy.

Main measures:

After the outbreak of the epidemic in Beijing Xinfadi market on June 1 1/2020, Chaoyang, Fengtai, Mentougou and Daxing districts successively started the wartime mechanism and entered the wartime state. According to public reports, the measures taken by various districts in wartime included killing and sealing.

Carry out "knocking at the door" and conduct a major investigation of people who have close contact with the Xinfadi market after May 30, 2020.
