How did the name of Chaohu Lake in China come from?

Chaohu Lake is the sixth largest lake in China, located in the middle of Jianghuai hilly area. Chaohu Lake covers a total area of 753 square kilometers. Its source starts from Yingshan and Huoshan, and the main rivers entering the lake are Fengle River, Hangbu River and Zhaohe River. Named after the shape of the nest. Chaohu Lake belongs to the Yangtze River system, and its water flows out of the lake in Chaoxian County and into the Yangtze River through Yuxi. In addition, Chaohu Lake was once an important traffic artery in ancient China.

Since the Qin and Han Dynasties, Chaohu Lake has been an important channel for traffic from Jianghuai to the north. At present, Chaohu Lake and Yuxi River are still open to traffic all year round. During the flood season, river water can be injected into the lake. The Chaohu sluice and Yuxi sluice built after the founding of the People's Republic of China constitute the cascade water conservancy hubs in Chaohu and Yuxi, which can protect the low-lying farmland in Chaohu basin from the threat of the Yangtze River flood. The agriculture in Chaohu area is relatively developed, and it has been one of the famous rice producing areas in China since ancient times.
