Passport expired. How to handle the valid visa on the old passport:

First, ensure the integrity of this long-term visa on the old passport. That is to say, when applying for a new passport, emphasize with the staff of the exit-entry administration that they should be "merciful" and not cut off these valid visas.

Generally speaking, when the staff invalidates the old passport, they will cut off a small triangle with scissors, usually the whole one. However, if there is still a valid visa on the passport, just talk to the staff and ask them to keep one or several pages of the valid visa intact, and just cut the corners of the other parts.
