Lingqu

The Lingqu () is a canal in Xing'an County, near Guilin, in the northwestern corner of Guangxi, China.

It connects the Xiang River (which flows north into the Yangtze) with the Li River (which flows south into the Gui River and Xijiang, the latter is one of the major tributaries of Pearl River), and thus is part of a historical waterway between the Yangtze and the Pearl River Delta. It was the first canal in the world to connect two river valleys and enabled boats to travel overland between Northern China and the Pearl River Delta. It is also one of the most well-preserved such projects in the world.
