The Qinhuai River used to be called Huai Water, and was renamed Qinhuai for the legend that Qin Shihuang, the first emperor of the Qin Dynasty (221-206 BC), ordered to introduce Huai Water to the city by excavating a mountain. It is a branch of the Yangtze River, running about 110 kilometers, a major watercourse aroundNanjing City. In ancient times, places around the Qinhuai River and the Nanjing Confucius Temple were already very prosperous. The banks along the Qinhuai River were the gathering place for noble and wealthy families, and were also frequently visited by scholars. Floating lights are the most famous view on the Qinhuai River. On the river, any boat or ship, large or small, will hang color lamps. It is a very important activity for a visitor to ride such a boat, floating on the river to enjoy the scenes.
