Take Route 1 or Route 4 from the train station and get off at Yujing Hotel on Xishuncheng Street. Then cross the road to the west and walk to the red light. Turn north for 100 meters and enter Jinhua Bus Station on the east side of the road. Ask about the bus to Yongkang.
Just take a ride.
The buses to the countryside all depart from there. I don’t know the specific routes, so I’m sorry.
