VISA expired, first of all, you have to judge whether your valid visa expired or your visa credit card expired! For visas, you need to know:

Need to apply for a new visa (passport must also have at least one blank page and must be double-sided! Passport is valid for not less than six months)

If you hold a China passport, your return to China will not be affected. China citizens do not need a visa to enter China.

If the VISA credit card expires, it usually takes some time to renew it at the issuing bank. In China, you can take it in a week or at that time, depending on the services and regulations of various professional banks. Abroad, in Europe, for example, at least two weeks.
