Introduction to Shenlong Valley: Shenlong Valley goes upstream, with ancient trees blocking the sun, mist swirling around, clever rocks densely covered, and deep pools and waterfalls. It is said that in ancient times, the cliffs on both sides of the canyon were like two natural stone gates that opened day and closed at night, tightly controlling the mountain pass, so it was called Shimenguan Canyon. A large number of strangely shaped boulders can be seen everywhere in the valley, which resemble the palace of the Dragon King of the East China Sea, so the valley is also called the Divine Dragon Valley.
