Introduction to Nantianmen: Located under the cliff of Nanshan at the pass of Yunmeng Basin, it is built on the stalactites of the cliff. It is divided into upper and lower floors and is composed of four pillars, shaped like a gate. The upper layer is a white-clad Guanyin naturally formed by stalactites. On the east side of Tianmen, there is a giant dragon carved with its head raised, looking at Guanyin, as if it is listening to Guanyin's instructions and is always ready to bring good luck to the world.
