Longcheng is a 600-meter-long, inwardly curved, south-facing geological formation of alternating tuff and basalt layers, shaped by millions of years of coastal erosion into a flat sea-eroded platform. The dynamic folding phenomenon, caused by the compressive forces acting on the lava flow during its movement and coverage, is enhanced by the three-dimensional effect of the fold lines, intensified by the varied colors of algae and moss. Overlooking the platform from the top of the cliff cone, green, white, gray, and brown curves meander across it, resembling a coiled dragon frolicking in the blue sky and sea, hence the name Longcheng.
