The formation of Butterfly Spring is related to the environmental conditions in this area. The spring is close to Cangshan Mountain in the west and the Bohai Sea in the east. Cangshan Mountain is tall and stands like a screen, the top of the mountain is snowy, and the summer is crystal clear. The clouds gather rain and precipitation is abundant. For example, Xu Xiake's long-suffering butterfly spring is summarized as "three absolutes": spring, butterfly, tree. Mountain spring, first of all, "quan". The water of butterfly spring is soaked from the sand layer of the rock seam. The water quality is particularly clear. When it comes out of the surface, it will gather into a pool without any pollution. The spring water from the butterfly spring is for people to watch. The largest pool is about 10 acres. The butterfly spring has changed from a pool in the past to a four pool. This is the most conspicuous landscape in the butterfly spring park. Butterfly, followed by "butterfly". In the butterfly spring, there are many types of butterflies. Every year from March to May, butterflies are as big as palms, and small as bees. They hang in a string of colorful acacia trees by the spring. Xu Xiake once described this in his travels: "There are thousands of real butterflies, even beards hooked feet, hanging from the tree and down on the spring, colorful, five colors. The trees, finally "trees". In the Butterfly Spring Park, there is "the beauty of butterfly spring is green, the pine forest, Berlin, Palm forests, tea forests, rhododendron forests, and Maozhu forests are also benefitted from local unique aromatic tree species such as Huanhuan and Huanglianmu by the butterfly spring. This night Huanhuan tree by the butterfly spring, whenever the flowering season opens in early April, the petals open like a butterfly during the day. The petals closed at night and spit out a burst of fragrance. The poet praised the butterfly as a "flower that can fly", and the flower of the amusement tree as a "butterfly butterfly". During the butterfly meeting, the flower danced with the butterfly, which is difficult to argue whether it is a wonder of the butterfly spring. The butterfly spring that makes tourists linger is too praiseworthy.
