In some areas of Ganzhou City, Jiangxi Province, which is also at the flood peak, the precipitation is nearly 100 mm, but there is no obvious waterlogging in the urban area, and even "no car is soaked in the water". At this time, Guangzhou, Nanning, Nanchang and other cities not far from Ganzhou were flooded, and some of them were nicknamed "Venice of the East" by the citizens. For a time, the inefficient and ineffective urban drainage system became the target of public criticism. All these differences stem from the urban drainage system represented by Fushou Ditch in Song Dynasty that Ganzhou City has played so far.

During the Xining period of the Northern Song Dynasty (A.D. 1068- 1077), an official named Liu Yi was appointed as the magistrate here, responsible for planning and building the streets of Ganzhou City. At the same time, according to the characteristics of street layout and topography, two drainage trunk road systems are built by adopting the principle of drainage by districts. He also left a famous saying "thousands of books is not as good as Wan Li Road".
Why today, with the rapid development of science and technology, human beings can sail interstellar, and the drainage system of modern cities is not as good as that of ancient cities? Is this because western technology is not as good as that of the East, or is there a congenital defect in our urban planning?
