Is the Ji'an Phoenix isolation point a single room?

Yes.

Jian Phoenix adopts the cabin isolation method, with one person in one room to prevent cross-infection of viruses.

A centralized isolation point is a place where single people live in a single room. During this period, they are subject to the unified management of the isolation point and are not allowed to enter or exit at will. Centralized isolation is an important measure to cut off the chain of transmission and implement domestic non-proliferation.
