Well, according to your landing time, you are advised to take shuttle bus night line and arrive at East Yan'an Road Middle Zhejiang Road first. The operating hours of this bus line are from 23:00 till 45 minutes after the last flight. Then just walk northwest around 900 yards to find People's Square.
