We (3 adults and 1 child) plan to visit China in 6-13 October 2010 with itinerary Shenzhen-Hangzhou-Shanghai-Beijing-Tianjin using train. Which pair city is most difficult to get train ticket? Is it sleeper class more available than seat class? Can we buy ticket for other city pair from first city station (Shenzhen)? Is it easier to get ticket for Shenzhen-Guangzhou-Hangzhou than Shenzhen-Hangzhou? Any other alternative route from Shenzhen to Hangzhou?
Thank you very much.
