My Changzhou nucleic acid sampling code cannot be loaded.

My Changzhou nucleic acid sampling code cannot be loaded. It is recommended to reopen the nucleic acid results. If it is not loaded, it is best to call.

My nucleic acid code registered in Changzhou cannot be used because the nucleic acid code is wrong.

The probability of an incorrect nucleic acid code is very small, but if you encounter this situation, you can call the prevention and control center to change the nucleic acid code and make a note in the system.
