Introduction to the original secondary forest: The collection of lakes in Guanluo Mountain is quite spectacular. The water of these natural pools mostly comes from the water sources bred by the original forests in the mountains. There are more than 1 million acres of primary secondary forest in Guanlui Mountain. These forests contain abundant water sources. When the water seeps into the ground, it flows into low-lying pits through gaps, forming a natural lake that never dries up or is filled with floods. Amazing.
