Night view of Qinhuai River in Nanjing

Qinhuai River is a tributary on the right bank of the lower reaches of the Yangtze River in China. In ancient times, it was called longzangpu. In the Han Dynasty, it was called huaishui. After the Tang Dynasty, it was renamed Qinhuai. The Qinhuai River has two sources: the Jurong River in the North originates from the south foot of Baohua mountain in Jurong City, and the Lishui River in the South originates from Donglu mountain in Lishui District, Nanjing city. The two rivers merge into the main stream of the Qinhuai River in fangshandai northwest village, Jiangning District, Nanjing city. They bypass Fangshan to the northwest to shangfangmen, the gate of the outer city, and flow into Nanjing city from dongshuiguan, crossing the urban area from east to west. The South flows out from xishuiguan and flows into the Yangtze River. Most of the Qinhuai River is located in Nanjing. It is the largest regional river in Nanjing. Historically, its shipping and irrigation functions have bred the ancient civilization of Nanjing. It is known as the mother river of Nanjing and is very famous in history.
