How to change Ankang code into Shanghai portable code

Changing Ankang code to Shanghai portable code requires re-applying for Shanghai portable code.

Ankang code and Shen Sui code can't communicate with each other. Every place has its own health code, and every place has a different health code name. Shanghai's health code is called Shen Sui code, Anhui's health code is called Ankang code, and Jiangsu's health code is called Su Kang code.

If you want to change to Shanghai code, you must re-register Shanghai code.
