Introduction to Jiulong Pond: At the top of Qianzhen Cave, there is a huge rock. The rock is flat and spacious, and there are nine pools of different sizes scattered inside the rock. These pools are as big as a bathtub and as small as a teacup. They are all crystal clear and neither waterlogged nor overflowing. Because it is said that this is the bathing place of the nine sons of the dragon, it is called Jiulong Pond.
