that is a lot of people. BTW, that building on Huai Hai Road (in the middle of photo) is one of my favorite buildings in Shanghai. When I first visited Shanghai in 1992, the building was in a terrible shape: rusty window bars, broken window glasses, laundry hanging out of windows/balcony, stains on the external walls, missing bricks. I am really glad the building has been well maintained in recent years.
