Why is Yunnan called the land of colorful clouds?
Second, there are many sayings handed down from ancient times, including the saying that the clouds are south. Yunnan is called "Dian" for short. During the Warring States period, it was the place where Yunnan tribes lived. Yunnan, meaning "the south of colorful clouds", is named after being located in "the south of Yunling". As the old saying goes, "A day is ten feet long, and Yunnan is in the sky". She is really close to the sky. 3 million years ago, a strong crustal movement caused the valleys in the depths of the ocean to suddenly rise, forming a strange plateau with vertical and horizontal peaks and streams. There is also a period of history that can be verified, that is, when the wonderful word "Yunnan" first appeared, it was not a provincial name but a county name. "Yunnan Tongzhi" contains: "During the Hanwu period, colorful clouds were seen in the south of China, and the name of Yunnan began here." "Nanzhao unofficial history" also contains: "Caiyun is now in Longxinghe Township, and the county is south of Caiyun, hence the name Yunnan." This county named "Cai Yunnan" is located in Xiangyun County, the gateway of western Yunnan.
