To do temporary identification: you can go to the nearest public security bureau or train station police station, as long as the passenger to provide identity card number and name can be. The temporary ID is stamped with the Public Security Bureau's seal and is valid for 15 days, and can be used for ticketing, access cards, and so on.
Presenting the hukou: As a valid proof of identity, the hukou is an important document that records residents' personal information, including their name, gender, and year of birth. In occasions where identification is required, such as for access cards, bank accounts, etc., and your ID card is not with you, you can use your hukou to authenticate your identity.
