The only place in Guangxi where ice and snow can be seen is known as the green gem on the Tropic of Cancer. Very abundant green vegetation. The Tropic of Cancer runs through the center, with Longtou Mountain, the main peak, 1761 meters above sea level, being the first peak in central and southern Guangxi. There are 120,000 mu of virgin forest and a variety of rare organisms in the reserve, which is a huge natural biological treasure house. The unique climate environment has created the four seasons landscape of Daming Mountain "spring flowers, summer waterfalls, autumn clouds, winter snow".
