Alipay health code has always defaulted to Beijing.

Alipay health code does not need to select the region and set the authority of the mobile phone every time, so Alipay can obtain the authorization of the location authority of the mobile phone. When you arrive in a new area, Alipay will automatically switch to the new area. If it is not switched in time, after opening Alipay and clicking the health code, the selected area will appear in the upper left corner. Just choose to switch to your area.
