What is the best and quick way from Crown Plaza Xia Yang to Shanghai city area?

Without knowing your exact destination, I assume you wanna go to the city center area near People's Square. I suggest you take a taxi for around 7.5mi to Sheshan metro station which is the nearest subway station from your hotel. There you can take subway line 9 to Xujiahui, where transfer to line 1 to People's Square.
