Huanglong is a very mature scenic spot. When walking out of the cable car, the first observation deck is encountered in the forward section. The clouds are dense in the distance, and the sun shines through the clouds from time to time on the distant peaks. The majestic cloud black pressure gathers on the top of the mountain, and there is a huge tiger coming down the mountain. A beam of sunlight makes the scene in front of you angry. Sure enough, Huanglong must have light, and light can show the various color levels in the water. The breeze gently slid across the surface of the water, sparkling, but the water was crystal clear and impressive, and the shore was crowded with people who took pictures. As the surrounding scenery changes and the angle of the sun changes, the pool changes into a multicolored color, which can be described as "the human pool." Huanglong travertine has a complete range of landscapes and is a veritable natural travertine museum. In the 3,600-meter section of Huanglonggou, the group is followed by almost all types of travertines, and subtly forms a golden "dragon" that plunges into the snow-capped mountains. I saw the size of the pool is different, the colors are beautiful and the water is flowing from the height to the low. The calcified rocks at the bottom of the pool are of different colors, so they show different colors and look very dreamy.
