Does Tongguan need to be isolated from Yang Shan?

Tongguan Huiyang does not need isolation. Tongguan is a low-risk area. According to the epidemic prevention and control policy of Yang Shan, it is forbidden for people in high-risk areas to return to the mountains, and the control measures of centralized isolation and home isolation in high-risk areas are strictly implemented. Other low-risk areas with epidemic areas need to implement closed-loop management.
