The water level of Huanglong Airport is about 3900 meters high. After a day and night, it has reached the Huanglong Scenic Spot with an altitude of over 4,600 meters from Jiuzhaigou. The cable car reached the top of the mountain and saw the colorful pool. The reason why it is called the colorful pool is because of its The water contains a variety of minerals. After receiving the refraction of sunlight, it reflects several different colors, including green, blue, red, yellow, green like jade, and blue. The sky, the red like the morning glow, and the yellow like the rapeseed flower make the lake look very different. I saw that the pool was connected one by one. The stone ladder at the first level was full of colorful water. The color of the water was the color that the paint in the palette could not recall. It was the color we could not name. The water of various colors is intertwined, as if it is a colorful silk. Looking at this beautiful scenery, it is really refreshing!
