Have you ever gone to book a train ticket online or at the station only to find out that you and your family aren't sitting together? If so, you'll be happy to hear that there's been a major upgrade to the booking system that would stop that concern.
A new system of train ticket booking in China was launched on Oct 12th. Under the upgraded system, alternative routes will be provided for passengers if the direct tickets are sold out and choosing seats online is available.
Choose Seats Online
Passengers travelling on C, D and G bullet trains will be able to pre-select their seats ahead of time. Meaning if you're travelling with friends and family you'll be able to sit next to them instead of 16 rows away.
If there are no neighboring seats left for your group to sit together and you absolutely have to take a certain train, you can also ask the system to automatically assign individual seats throughout the train for you.
