Including Xanadu, Happy Valley, and the Yuzu Memorial Hall. Xanadu must go to Wangjiang Pavilion first, and Baima Cave (karst cave) finally go, because Baima Cave is the tunnel entrance of Happy Valley when it comes to the end, and after the tunnel, it is Happy Valley. The Longquan Cave (karst cave) in Happy Valley will charge an additional ticket of 26 yuan. Happy Valley is the back door from the road on the opposite mountain, and the back door is the main entrance of Sanyoudong. The regular price ticket for the Yuzu Memorial Hall is 30, and there is nothing to see at all.
