We are coming to Shanghai on January 28 until February 4 (2011)as tourists. We plan to catch a train from Shanghai to Hangzhou on January 31 and return to Shanghai on February 3, and we have booked all our hotels in Shanghai and Hangzhou for our whole stay in China (one week). Will we have trouble getting trains on the specified days? I understand February 3 is New Years Day - is this a public holiday in China?
