Can I travel when my ID card expires?

An expired ID card is considered invalid, but it will not have much impact on travel. If you are taking a domestic flight, you can first go to the airport or the public security bureau to apply for a temporary ID card. If you are taking an international flight, you don't need an ID card, just a passport.

Purchasing train tickets, bus tickets, travel tickets, etc. can be used normally even if the ID card expires. Expired ID cards will not affect accommodation issues.

If you are really worried about problems, you can apply for a temporary ID card first.
