2. Yuyuan Garden includes Shanghai Old Street, Chenghuang Temple, Yuyuan Mall and Yuyuan Garden, which is enough for a whole day. Set aside some time to go to Tianzifang not far from Yu Garden.
The first day's schedule was so tight that it was almost too late. I don't know why I had breakfast in Raffles. This makes the route detour, and the traffic in Shanghai is so congested. Hongqiao Railway Station and Songjiang University Town are in the suburbs, Hongqiao is in the west and Songjiang is in the southwest. Raffles from Hongqiao to downtown had breakfast and then went to Songjiang. It's estimated to be 2 or 3 o'clock in the afternoon.
Suggestion: Walk 400 meters from Hongqiao Railway Station to Hongqiao Hub Transportation Center, take Hongqiao Hub Line 4 to qibao station and transfer to Metro Line 9 to Songjiang University Town. Try to return to the city from Songjiang around noon, visit IKEA and Xintiandi, and go to hengshan road at night.
