Then state your legal rights and obligations and the corresponding legal consequences. And ask you to guarantee all the facts and so on.
Later, I asked some questions about land, such as who is the owner of the land, the location and area of the surrounding boundary, the type of land, whether the ownership certificate has been obtained, and whether there is a contractor. When did the illegal act start and who did it, such as filling soil, construction and so on.
Finally, ask if you have anything to add, then sign your name and put your fingerprints on it.
That's basically it.
It is illegal not to show your identity and certificate first. The law enforcement process is invalid.
