As a witness, I have to go to the police station to make a statement. Will my home address and personal name be kept secret? Is there an express provision in law? urgent

Relatively confidential, but the defender's lawyer has the right to read the papers and can read them.

See Article 61 of the Criminal Procedure Law for the explicit provisions of the law, which stipulates that the people's courts, people's procuratorates and public security organs shall ensure the safety of witnesses and their close relatives. ......

In addition, there should be no special confidentiality provisions, because public security organs, procuratorates, people's courts and defenders can see them. But other ordinary people have no right to see it.
