Sichuan basin. It flows through
Jintang, Jianyang,
Ziyang,
Zizhong, and

phosphate mining waste, and further rapid industrialization in the 1990s cause the river to become one of the most polluted rivers in Sichuan. In 2022, the river's water quality significantly improved, following implementation of
environmental protection policies in Sichuan province. ==See also==
