Introduction to colored stones: The reason why it is called Colorful Jade Valley is because the stone here is colored granite formed after volcanic eruptions. After millions of years of erosion and erosion by water flow, the rock mass on the surface of the colored stone layer was pushed away, and the colored stones were exposed. They are mainly brown, red, and pure white, with green, blue, gray, and other colors in between. Black and other colors are gorgeous, and the entire river bed is like a jade belt. As the light and projection angle change in the morning and evening, sunny or rainy, and in four seasons, the colorful jade valley also produces different tonal viewing effects, just like the changing background of a modern stage.
