Plane Tickets / Train Tickets / Attractions Tickets
In China, there are official websites and apps for booking train and plane tickets:
Attraction tickets may be sold through an official website, an official WeChat mini program, or a major booking platform. The correct channel and foreign-passport support vary by attraction.
China Railway 12306 has an English website and app, but some local attraction channels remain Chinese-first.
Real-name services may ask for passport details or identity verification. Complete setup before tickets open whenever possible.
The China trains and transport guide explains passport verification, station names, boarding, and local transport in one sequence.
