Nujiang, flowing through the vicinity of Ridan Village, Bingzhongluo Township, Gongshan County, Yunnan, due to the barrier of Wang Yuda Suspension Rock, the flow of the river from north to south to east to west, more than 300 meters after the flow, and was blocked by Danla Mountain, so I had to turn around again from west to east. A semicircular bay is formed here, called the first bay of the Nu River. There is a village in the center of the bay called Kantong Village. The river is more than 1710 meters above sea level. It is magnificent. The Nujiang platform on the bay is flat and open, 500 meters higher, forming a peninsula-like small plain surrounded by water. The small plains are pleasantly surrounded by scenery, and the pastoral scenery is everywhere.
