Introduction to flying stones: The third pool in the middle of Jiulong Pool is far away from the fourth pool, and the slope is steep and wide. A hanging water curtain flows from the fourth pool to a waterfall. Falling into the third pool, the water rushes down, splashing water, and then bypasses a huge boulder in the pool, forming a new water curtain, and pours down. The boulder overlooks the rapids rushing away, and the scenery is very spectacular. This stone buckled on the edge of the third pool has a unique shape and is lonely and helpless. It is called the flying stone.
