Do I have to go to the hotel for isolation without compulsory isolation?

Non-mandatory isolation can choose to isolate at home instead of going to the hotel.

Compulsory isolation: From the perspective of public security law enforcement, compulsory isolation refers to an administrative compulsory measure enforced by the local public security organ when the public security organ isolates some patients with infectious diseases, or isolates infectious diseases from specific people or individuals to cut off the source of infection.
