It has been nearly four years since a fishing ban was implemented on the Chishui River, the only primary tributary in the upper reaches of China's longest river of the Yangtze that has not been dammed. The river is home to an abundant resource of aquatic creatures. Since January 1, 2017, the Guizhou part of the Chishui River has been completely closed to fishing for a period of 10 years. Over the years, the river has undergone dramatic changes. The local government has also made the protection of the Chishui River a common goal for all residents.
