How I reach Ji Hotel Shanghai Railway Station west from PVG after 7pm?

You can take shuttle bus line 5 and get off at the terminal station - South Square of the Railway Station. Then walk to the hotel in 5min. The bus stops running at 23:00 by the way.

Or take subway line 2 to People's Square and change to line 1 to the Railway Station. Then your hotel will be within 900yd away.
