Introduction to Colorful Jade Valley: Colorful Jade Valley, formerly known as Xianyu Grand Canyon, was formed about 340 million years ago. In this colorful canyon about 4,000 meters long, especially the brown-red stones, as smooth as jade, are extremely gorgeous against the backdrop of the water. There are also two huge natural murals in the Colorful Jade Valley, one of which is nearly 100 meters long, majestic and shaped like characters and rare birds and animals.
