The reason why Zhengyifang was blocked is that, according to the official news, a man flew to Kunming from other provinces (it should be Shanghai), and his health code was already red, but he used the "screenshot of green health code" to deceive epidemic prevention personnel all the way. After landing in Kunming, he went to four or five crowded places. Finally, he was found to be a screenshot by security personnel in a bar of Zhengyifang, and immediately reported it to epidemic prevention workers. The man was controlled and passed through.

Zhengyifang is located in Zhengyi Road, downtown Kunming, which is located in the golden business district of downtown Kunming. It is a large shopping and entertainment place in Kunming.

Justice Square is mainly divided into South Pavilion and North Pavilion. There are two floors underground and five floors above ground. The first floor is Taobao Street, which mainly deals in clothing department stores. The first floor owner should deal in branded clothing and jewelry. Upstairs are mainly clothes, food streets and cinemas.
