I come from Wuhan. I want to go to Hangzhou this winter vacation. How many days should I buy the train ticket in advance?

From Wuhan to Hangzhou, the first choice is Z45, Wuchang-Hangzhou City Station. Depart from Wuchang at 0: 00 in the evening/KLOC-0, and arrive at Hangzhou City Station at 6: 30 in the morning. Sleeping berth is only 230 or 8 hours, which is more convenient. Just need to sleep. I always choose this. It's the same when you go back, Z47. It departs from Hangzhou City Station at eleven o'clock in the evening and arrives in Wuchang at seven thirty in the morning. There are many people in this car, so you'd better buy it 1 1 day in advance.
