We are planning to catch an overnight train from Xian to Beijing on Tuesday 30 April.

Can we pre book this online and which website is best for this as I am finding it all a bit confusing. We are staying at the Tiananmen Best year Courtyard Hotel in Beijin (1 Denglong Ku Hutong Nanchizi, Beijing) on arrival and would like to know which train station we should get off at. Thankyou
