Introduction to Zhuling Cave: Going down the stone steps next to Hejiang Pavilion, there is Zhuling Back Cave on the cliff. It is said that this cave is similar to the Nanyue Water Curtain Cave with the "Zhuling Cave Sky". According to the Records of Hengzhou Prefecture, there were original Tang Dynasty handwritings and poems left by tourists from past dynasties in the cave, so there is a saying that there are "thousands of poems in Zhuling Cave". However, it is difficult to see writing in the cave today, only the right one outside the cave door. The words "Zhu Ling Hou Cave" below are said to have been written by people in the Tang Dynasty.
