Hangzhou west railway station to Wuzhen

Hello
I have seen there are buses going to Wuzhen from “Passenger Transport Central Station (Jiubao Passenger Transport) but I have not seen the frequency and schedules.
I have seen also that to go from the HZ west railway station to the “Passenger Transport Central Station (Jiubao Passenger Transport) you can take the subway line 1 and just five stations.
Can you assure me it is a good practical way to go to Wuzhen.
I need to know the latest bus schedules and how long it takes before I decide which train I will choose from Xiamen to Hangzhou.
Thanks for your information
