Chashan, formerly known as Dongshan, is a geomantic treasure land that was favored by the Queen Mother of the West. The Queen Mother of the West sent the mountain god to transform into a Taoist priest and established a temple here, which is now the site of the Prajna Temple. Three tea seedlings were also planted next to the "Zhuangyuan Well". After being nourished by the essence of heaven and earth and the spring water of the tea mountain, the tea seedlings flourished and were several times taller than ordinary tea trees. It took several people to hold the stems. There are dozens of acres of tea trees in the shade, which is a wonder in the world; the fragrance of tea is very strong, and the stream of tea mountain is also clear and sweet. The tea leaves flow down the stream, and the fragrance of tea is overflowing. Those who smell the fragrance are healthy and drink it. Tea drinkers have sharp ears and eyes, so people from far and near praise it and its reputation is also very good, so Dongshan was renamed "Tea Mountain". But the magic of this tea tree has aroused the covetousness of bad people, who want to take possession of the tea tree for themselves. The tea tree is guarded by a spiritual snake. A bad guy inserted a sharp knife upside down on the snake's way to drink water. Unfortunately, the female snake's abdomen was cut open by the sharp knife without realizing it. The male snake used tea powder to heal his wife's wounds. The tea god appeared and saved the female snake.
