Lion Rock Introduction: Mingyan is a deep valley sandwiched between two hills, about 50 meters wide and one mile deep. It is famous for its strange rocks and strange caves. At the mouth of the valley, the Zhexi River flows south. 50 meters to the left of the entrance is Lion Rock, commonly known as the Gathering of Five Lions. There is "Qiyun Cave" (commonly known as Shizikou) in the valley. The cave is named after the rock walls on the top of the cave have patterns like clouds and mist flying. Inside are Guan Gongxiang and Xianshui Well. Xianshui Well, also known as Sun and Moon Well, is inexhaustible in all seasons and contains 24 kinds of minerals, which are of great medicinal value.
