The window of the central isolation hotel can't be opened.

You can give feedback to the isolation staff and see if you can change rooms.

During the isolation observation, you should live in a single room, strengthen indoor ventilation, and open the window for ventilation more than twice every morning and evening for more than half an hour each time. Wastes generated during isolation, such as masks and personal hygiene-related items, should be put into the designated covered trash can.

If the windows of the isolation hotel can't be opened, you can apply to the three-person group or the isolation hotel for room change. If there are more rooms, you can change rooms.
