I’m staying at the Salvo Hotel in Shanghai and I need to catch a train to yiwu - from which station would I catch the train?

Trains from Shanghai to Yiwu are departing from Shanghai south station or Hongqiao train station. Salvo Hotel Shanghai is around 15km to South train station while 23km to Hongqiao station. If you’d like to take the bullet train to Yiwu, you could take subway line 2 to Hongqiao station directly.
