Airplane is landing at Hangzhou midnight. What should I do?

Hi all. I have a flight to HZ landing around midnight or after midnight (i am not sure because the flight company which i booked always delay taking off time). Afterward, I have to move to Jinhua. Do guys have any idea for me at the night? I really want to go to Jinhua after landing but is there shuttle bus or train to Jinhua at night? if not, can I stay at the airport at that night to wait for the working time of bus or train? I hear that there are some hostel near airport, but it is so expensive. Thanks all and warmly welcome your recommendations!
