Does Pucheng epidemic category D need to be isolated?

The D-level secret workers in Pucheng are in yellow code, and the yellow health code represents the need to implement home isolation for medical observation.

When people with code yellow or red team enter the low-risk area, they can automatically record the time of arrival in the low-risk area as long as they turn on their mobile phones. After quarantine 14 days, the health code will automatically change back to the green health code if the person who owns the code has not become a secret contact or COVID-19 case.

Holding a green health code means that you can go in and out normally when your body temperature is normal and your personal protection is good. The red health code means that the code holder needs centralized isolation, that is, it needs to go to the designated isolation point for centralized isolation.
