Railway station to west bus station in Hangzhou

From the railway station, you can find bus line 49 to reach the West Bus Station directly. It takes you about an hour on the bus journey.
Hupanju Tea House is a good place to have a lunch.
From this tea house, you can walk to reach Xiaocheqiao Station on Qingchun Road to take bus 49 to reach the West Bus Station.

Thanks for your suggestion. How frequently does Bus 49 run?

My Chinese friend says that the bus operate every 4-6min during rush hours and the interval is 7-10min in normal time.

Thanks Lydia
