The above is an allusion. I saw a travel story. The author said that at noon, when I entered Tengchong City, which is known as "the first city near the pole", the rain had stopped suddenly, and the MM around me suddenly screamed, "Rainbow, rainbow, rainbow ..." The horizon, a complete rainbow across rivers and hills, was clear and dreamy, and even people watching it could distinguish the texture of purple edge and green edge. As the car body moves, it seems to be approaching and drifting away. Finally understand the origin of colorful Yunnan.
Hehe, this is the official personal experience.
Another allusion: Yunnan, which means "south of Yunling", is also called "Yunnan". According to legend, in ancient times, God planted a handful of hot land in the southwest of China, forming a continuous mountain range; Dump a bowl of nectar to form dotted lakes and criss-crossing rivers; Oh, fairy dust forms colorful clouds. This is the origin of "colorful Yunnan".
