China has high speed rail. When you enter the train station security checks your national ID then screens your person and belongings. Buying a ticket requires scanning ID. Going from the station down to the platform requires scanning ID. On the train sometimes police come aboard and check everyone’s ID. When you get off the train you have to scan ID. Riding the bus or subway was one of the very few things that does not require scanning national ID or registering an account linked to national ID. However if you ride a bus into Beijing there are checkpoints requiring everyone to get off, get searched and show ID.
