Introduction to Tianyuntan: There is a big stone in the pool. Legend has it that it was formed by wrapping the phoenix dandruff in the spit of a dragon. The pool under the waterfall on the east side of the stone is called the wash basin, and the pool under the waterfall on the north side is called the Zuozu Pool. Legend has it that there were two sisters-in-law who were unable to have children for many years after their marriage. Later, the sister-in-law accidentally washed her hands in the east pond and became pregnant and gave birth to a daughter. The younger brother and sister washed their feet in the north pond and became pregnant and gave birth to a son. From then on, many people came here to wash their hands and pray for their daughters and wash their feet for their sons.
