Introduction to the Great Immortal Chaya: The Great Immortal Chaya is the legendary founder of Mount Chaya. Legend has it that a long time ago, there was a flood here. In order to stop the flood, the Great Immortal Chaya threw down the stones from a rockery in the Queen Mother's back garden one by one, and piled them up to form the current Chaya Mountain. In order to commend his merits, the Jade Emperor entrusted him with a dream. The emperor of the current dynasty named this mountain Chaya Mountain.
