The essence of Huanglong Scenic Area should be counted as a "colorful pool". Entering the scenic area of Wucaichi, a sculpture of 162 to 163 pages of Chinese texts of primary school students in "Wucaichi" appeared in front of me. I read it in full: "I heard my grandmother say when I was a child, there is a Kunlun Mountain in the West, and there is a Dianchi Lake on the mountain. It is the place where the gods of the sky live. The water in the pool is very beautiful, there are five colors, red, yellow, green, blue, purple. ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... The surface of the stone is condensed with a fine and transparent stone powder. The sun shines through the pool water to the bottom of the pool, and the sun reflects into various colors like a refracting mirror. The trees and flowers around the pool are very lush, and the reflections of the colorful colors make the pool more magnificent. The colorful Dianchi Lake is on earth, not in the sky.
