Penglai River Nature Park is full of precious ecological resources. A few years ago, a couple of local residents were concerned about the ecological health of the Penglai River, so they built up a team to protect the river from poisoning and electroshock fishing. Also, they built a 1.6 km trail along the River with rocks and wood for tourists to hike. Now the water is clean and so clear that you can see fish all along the River.
