Introduction to Jiaolong Cave: The canyon is densely covered with primitive secondary forests, interspersed with streams, ditches, waterfalls and flowing springs. Whenever the sky clears after a rain, countless white fog pillars appear in an orderly manner. The breeze blows and the fog pillars sway with the wind, resembling dragons soaring into the sky. The strange fog in Jiaolong Cave is the first fog in Nanshan. It is like entering a maze when you are there.
