Does Qingyang come to Yinchuan for isolation?

No isolation. According to relevant sources, except for self-examination in low-risk areas, Yinchuan will implement centralized isolation medical observation 14 days for all people who have lived in Nanjing, a middle-high risk area, and Qingyang will be basically a low-risk area by September 6, 2022, so there is no need to isolate them when going to Yinchuan.
