The first bay in the 99th Daowan Bay of the Yellow River, which merges with the Baihe River in Tangke Township, Ruoergai County, Sichuan. The Yellow River here is clear and slow, passing through the vast sea of grass, and the leisurely stroll of cattle and sheep by the river is the most beautiful corner of the 99th bend of the Yellow River and the most breathtaking natural wonder.
