I would like to go by train from Shanghai to DongYang, what is the way to do that?

There is no train station in Dongyang, Zhejiang Province. By train, you could take one at Shanghai south train station or Hongqiao station to Yiwu first, which is around 20km away from Dongyang. After getting off at Yiwu train station, you could take a bus to Dongyang directly.
