Beneath the South Tianmen Gate, there is a boat-like Wolong Stone, a famous flying boat, lined with drifting clouds. It is like a boat breaking waves in the sea of clouds, while the stone archway of the South Tianmen Gate is a towering mast. The archway is divided into the middle gate and the left gate, the right gate, and the upper banner of the middle gate is marked with "Nantianmen" three large red characters. The left and right lintels are inscribed with "Xingyun", "Shiyu" and the handwriting is striking.
