Two options:
Take a seat at Hangzhou South Railway Station, and then transfer to Wenling. Wenling train is in zeguo town, so you have to transfer to a bus to get to Taiping in Wenling County. There are many motor trains and they are fast. You can also take a bus from Hangzhou East Bus Station to Wenling, which takes about four hours. However, it is quite far from Hangzhou South Railway Station to Hangzhou East Bus Station, which is not recommended.
Second, take a seat at Jinhua West, the terminal, and then transfer to Wenling. After getting off at Jinhua West Station, go straight to the right for 200 meters and get on at West Bus Station. Ignore those who put up slogans at the railway station to attract customers.
