Dude, I'm customer service. Just fax the certificate to any agent. The form of the certificate is not limited, but it needs to be convincing. For example, if the company issues a certificate, whether you rent a house or live in a company dormitory, just stamp the official seal of the company. It can also be a certificate issued by the neighborhood Committee that you belong to public rental housing or no housing. Anyway, the form of the certificate is not limited. What certificate do you think you can get? If you send this to the agent, you can modify it. It will be uploaded to the People's Bank in about a month, so that the nature of the house in the credit can be changed.
