The passport information is submitted when purchasing train tickets. May I use my ID card to take the train at the station?

When going to the station to take the train, if you submit your passport information to buy a train ticket, you usually need to show your passport to go through the station entry procedures. The ID card is China’s resident ID card, and the passport is an international travel document. The train ticket system will match the corresponding document based on the type of document you provide. So, if your train ticket was purchased using your passport information, you will need to show your passport instead of your ID card. If you do not bring your passport, it is recommended that you contact the ticket purchase window or railway customer service as soon as possible to learn how to handle this situation.
