Chinese trains must be quite heavily subsidized. In general, I don't like having to book a particular train instead of a route, just because of the extra mental planning overhead, but with the free rebooking it may be bearable.

> if you miss your train, you can still cancel it and rebook a later train with only a 20% penalty, as long as you do it within 24 hours of your scheduled departure.

This, this is amazing. How I wish the SNCF did it like that. (Actually, it happens often enough that all SNCF trains on a route on the same day are booked full so maybe it wouldn't help.) When you are early, can you also up- or downgrade at no cost (other than the price difference), e.g. if only seats are available in a different class than on your ticket?
