Under what circumstances will the property call the owner and tell him that he must leave someone at home today?

Hello, my friend, this situation is rare. General notices are posted on the stairs. If it's a phone call, be sure to leave someone behind.

For example, the heating test must keep people at home, water meters and electric meters should be inquired, and there must be someone at home. Complain about water leakage in your downstairs, and you need to leave someone behind.

But don't worry.
