I found something on the street, and I have no contact information. How can I find the person who lost it?

I'm not kidding you. Every city has a lost and found center. If the police can't find it or are too lazy to find it, they will usually hand it over to that center. If the owner calls the police to look for the lost property, the police will give him the phone number of the lost and found center. Beijing is like this, I don't know about other places. Moreover, if something is found and not handed over to the police station, it objectively constitutes illegal possession, and the property law has the definition of finding lost property. Leave it to you, the master is really nowhere to be found.

So I think it is the most reasonable and legal way to give it to the police uncle.

I am willing to help others, but if you don't have a clue, I can't help you find it.

I was laughed at for trying to help. These days, .....
