Introduction to Immortal Cave: Legend has it that the ancestors of the Yunshe Tujia family originally lived in Shengxisi. Through the hard work of several generations, the family has continued to grow stronger, but it is difficult to find a better place for future generations. People lived there, so they killed pigs and sheep to pray to God. Seeing how loyal they were, the immortals gave them the Yunshe where they originally lived to build a new home, while they retreated to the cave behind, so it was called "Immortal Cave".
