Although Changguangxi River has a long history, it's located in outer suburbs and most wuxiese are not familiar with it. I came to know about this name because of the construction of the university city near it in recent years.
Taihu Lake is at the southwest of Wuxi. Changguangxi River since ancient times has been a short cut from outta Wuli Taihu Lake to Wuli lake to enter Wuxi City. The meaning of it's name was originate from "wide stream long river" . It starts from the north at Shitang Bridge at the entrance of Wuli lake, flows through Dongjiang, Xuelang, Nanquan and other places, turn west runs into the Taihu lake passing Wutangmen, with a total length of 12.73 kilometers, 15-40 m wide, 1.3 -1.7 meters' depth in dry seasons. The river water is from Xuelang and other mountains and the nearby rivers, but because of farmland, water area had reduced for several times.
Changguang River is also known as "hundred feet river", for there were many small rivers running vertically and horizontally as Hezhuangbang, Xuelangbang, Changshubang, Xushebang, Hongqiubang, Wutangbang and many others. When there's a rain, water from four towns flow into Changguangxi River and runs into Taihu Lake; When there's a the people of Taihu Lake; When it's dry, the rivers irrigate tens of thousands mus of grain of the cross-strait area .
The history of Changguang River can be traced back to the Three Kingdoms period.
