Introduction to Yuhuayan: One of the four wonders of Guifeng, it is located under the Painted Wall Peak of Guifeng. Raindrops continue to fall from the top of its mountain all year round. The continuous, fluttering raindrops are refracted by the sun, like colorful petals falling into the world, and the scene is very spectacular. There is a beautiful legend about Yuhua Rock, and this rain flower is not an ordinary rain flower, but was changed from the tears of Baolian, the third princess of the Dragon King of the East China Sea.
