Since ancient times, legends and fairy tales such as the Legend of the White Snake, Liang Zhu and Su Xiaoxiao have been circulated in the West Lake. In The Legend of the White Snake, such plots as "Meeting at the Broken Bridge" and "The White Snake is crushed to death by the Leifeng Tower" are all related to the ten scenic spots of the West Lake.

According to legend, Yulong and Jinfeng in the sky found a piece of white jade on Xiandao near the Milky Way. They pondered together for many years, and white jade became a bright pearl. Wherever this orb goes, trees are evergreen and flowers are in full bloom.

However, when the orb was discovered by the Queen Mother, the Queen Mother sent heavenly soldiers to take it away. Yulong and Jinfeng hurried to get the orb, but the Queen Mother refused, so a fight broke out. As soon as the Queen Mother's hand was released, the pearl fell to the ground and became a sparkling West Lake. Yulong and Jinfeng also descended to the world and became Jade Dragon Mountain (Jade Emperor Mountain) and Phoenix Mountain.
