Longxu Ditch
The 883rd longest river in the world
Longxu Ditch, formerly known as Jiaotan Houhe, is a man-made drainage river in the south of Beijing, built in the Yongle period of the Ming Dynasty. After the Qing dynasty, Longxu Ditch gradually reduced to a sewer, with the nearby community becoming a slum. In 1950 the Beijing Municipal Sanitation Engineering Bureau cut off its source and the surface of the river completely disappeared. Lao He created the drama "Longxu Ditch" for the renovation of Longxu Ditch in 1950.
