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 here is formed, called the first bay of the Nu River. The first bay of the Nu River is magnificent and natural, and it is known as the "last secret of Yunnan". Here is the wonder of nature, and tourists can't help but sigh and rush to take pictures.
