Another attraction worth visiting, I took the whole family together. Everyone was very happy to play. A natural cave on the mountainside next to Baishiya Temple is said to be unfathomable and can always lead to Sichuan. Due to the dark and clean interior, many monks have entered the inner practice. You must let the lama take in at the ticket office. The hole is muddy and you can use it with your hands and feet. It is recommended to wear dirty trousers. It is best to bring your own flashlight (you can also rent it at the ticket office).
