Why should I open Tencent Health? My health certificate shows Shenzhen.

Tencent Health Card shows that the Shenzhen system has not been refreshed. If you want to switch the health code city, first open the Tencent Health app, click the health card option on the Tencent Health page, select the region in the upper left corner of the health card page, select the province and then select the city, and click View Now to switch successfully.
