Introduction to the wonders of Longtang: Longtang, also known as Bengpotang, is located in the North Wanshan Mountains of Pingyong Town, Rongjiang County, 47 kilometers away from the county seat. It is the first scenic spot in Rongjiang tourism.
The water area of Longtang Lake is about 140 acres, and the deepest water is 24 meters. It is about 4.5 kilometers to walk along the pond. It is surrounded by strange mountains, covered with pines, bamboos, peaches and plums, and the lake has green waves. The scenery is extremely charming. It was formerly known as the "Little West Lake" . After the beginning of autumn every year, the pond water appears in three colors, either green, yellow, or black. Sometimes, there are three colors in one day, and the three colors change into each other, which is strange and abnormal.
