Is Cangzhou Tianjin to Chengde paddock used for nucleic acid detection in 221?

nucleic acid testing must be done from Cangzhou and Tianjin to Chengde paddock, because Hebei Province is now experiencing a high epidemic. If there is nothing wrong and there are no special circumstances, don't travel, especially in these cities near Hebei, stay at home! Be responsible for yourself, for arguing, and for the country.
