easyist way to go from hangzhou to yiwu in night at 9 p.m..

There is no direct buses to reach YW during that time, because it is so late. The last bus from the airport to YW is at around 21:30, so if you can catch it, it is suggested to catch it. So it is suggested to stay one night in Hangzhou, if you cannot catch the last direct bus from the airport.

If you have to reach YW at night, you may choose to take the ordinary K-trains from local railway station and some of the trains are before tawn.
