Leaving the prevention and control area to allocate coding delay

Leaving the prevention and control area will be delayed, because after entering the new area, you will receive a health reminder message first, and then the health code will be assigned a yellow code for more than 7 days. If there is no exception, it will automatically turn into a green code.

Coding is a unified electronic supervision measure for products implemented by China government, which is to give each product a unique identification (supervision code).
