Introduction to Yuquan Gate: Yuquan Gate is a natural stone gate standing not far from both sides of the Ziniu column. It is more than 350 meters high, with thousands of cliffs on the left and right. It has been 5 or 6 billion years ago. The two stone doors of Yuquan Gate are like half-opened doors. From time to time, refreshing mountain breeze blows in, bringing a little bit of coolness to the hot summer.
