Introduction to Guantangou: Guantangou is the former site of King Su's horse ranch in the Ming Dynasty. It was formerly known as "Sufu Guantan" and now there is a boundary sign of "Muma Guantan". There is a valley sandwiched between two mountains in the area, with a forest coverage rate of 86.2%. As the altitude increases, artificial coniferous forests, secondary broad-leaved mixed forests and alpine shrubs appear successively. The colors change throughout the seasons, and the forest environment is colorful. Full of wild fun in the mountains and forests.
