Late night bus from HongQiao to Hangzhou?

Actually, at late night, there is no public bus. The private buses around there may overcharge at night, but the price will not be too high. Just negotiate with them for a flat rate before boarding in case of being scammed. You can take one, or you can stay nearby overnight and in the next day by a bullet train or bus to your destination (the first bullet trains leaves at 06:30 in the next morning).

Thank you. This is helpful. Wish there was another way, or more late night trains.

Hello again, Warren. I just noticed that the last normal train leaves from the South Rail Station at 23:32. Upon landing at Hongqiao, you can take a taxi to the train station in around 20min, at a cost of CNY50 and catch the train. It takes around 3h and 40min. Hope this way suits you.
