Your uncle's guarantee is also legally liable.

Suggestion: the bank has come to collect debts, and the five-guarantee households have no money for your uncle to pay back. This is not right. 1. The five-guarantee households have not escaped, disappeared or lost, and the main responsible person is still there. Banks should first offset and pay off the assets of the five-guarantee households through litigation. You can ask your uncle to make up for the shortfall. 2. Looking for your uncle now obviously violates the procedures of the guarantee law and the bank. If you come again, call the police and tell the police that the bank illegally invaded the house. 3. Your uncle should talk to the five-guarantee households and try to make him not cheat, because his assets can be executed.

There are local regulations in various places, and your government may not be willing to crack down on the five-guarantee households, which is better. If he doesn't pay back, he won't execute it, and the case will be suspended, which is good for your uncle.
