What are alternatives if my route isn't available?
Don't sweat! Here are just some of the friendly tips Klook can offer if you find you're unable to book your train route:
Try to book a few stations further from your destination and get off the train earlier. China Rail sometimes allocates tickets by stations, so you might get a seat. Of course, you will have to pay an additional fee (and this trick does not always work).
You could also check back regularly since there might be tickets released as other passengers cancel or amend their tickets.
