In the western district of Shanghai, which is very poetic, there is a building called "Bai House". The tall trees and elegant environment make the road scenic. Most of the small western-style buildings by the road have a long history, such as the residence of the president of the French Concession Public Council, the Jewish Club, the old residence of Ding Guiyang and Pan Chengbo. When you unintentionally step on the fallen leaves here, you may hear the sound of piano or violin like running water. Behind the strong wutong trees, there are quiet gardens. A number of western-style buildings with different styles and exquisite postures are hidden in them… One of these buildings is Bai House.
