What if the ten-year visa passport issued by China and the United States is about to expire?

China and the United States have issued a 10 visa. When the passport expires, they should apply for a new passport at the entry-exit reception hall of the county-level public security bureau where their household registration is located. At that time, if the visa of the old passport expires, they can continue to use it. The specific provisions are:

Article 13 When issuing or renewing a citizen's ordinary passport, the exit-entry administration organ of the public security organ shall declare the original ordinary passport invalid. When the ordinary passport is renewed, the upper right corner of the original ordinary passport of a citizen shall be cut off;

If the original ordinary passport has a valid entry and exit permit, you can cut out the back cover and the upper right corner of the cover and return it to me.
