Can Xi 'an B-class children go to school?

I can't. Children of close contacts refer to those who can't go to school for the time being and should be isolated at home 14 days, or isolated at centralized isolation points. At present, we must not be careless during the epidemic, and we must consciously abide by various policies, which is good for the country and ourselves. Nucleic acid should be done regularly during the isolation period, and if there is no problem at that time, you can resume your study or class.
