Should Yangquan, Shanxi, return to Quyang, Baoding, Hebei, be isolated?

Yangquan, Shanxi, and Quyang, Baoding, Hebei, must have locally made nucleic acids, which are valid for seven days. Isolation at home at the same time 14 days.

Don't go out unless necessary, don't go to high-risk areas and/or areas infected by positive people, don't go to counties (cities, districts) where high-risk areas are located unless necessary, and don't go to foreign epidemic areas. Going to Baoding and Quyang requires negative proof of nucleic acid test within 48 hours, and the health code is "green code".
