Introduction to Shuiliandongtian: Shuiliandongtian is surrounded by thousands of walls. The water curtain pours down from a height of 30 meters into a round pool, shaped like a patio. There are four "Shuilian Dongtian" on the cliff. The calligraphy was written by Comrade Qi Tianfu. On the stone wall more than 20 meters away from the pool, there is a waterfall viewing pavilion. From the pavilion, you can see the panoramic view of the water curtain cave and sky. Whenever the sun shines slantingly, a rainbow lies in front of the curtain, colorful and dazzling.
