Introduction to Huayuyan Alley: Huayuyan Alley is a wonder in the Zangdao River Scenic Area, located in the Lamao River section upstream of Qianmaokou Canyon. The rock lane is about 500 meters long and only 15-20 meters wide. The cliffs on both sides stand more than 300 meters high, forming a lane-like canyon with cool breeze and sparkling waves. There are towering ancient trees on the cliffs on both sides, a line of blue sky, and fine wine falling from the sky. The mouth of the gorge stands tall like a giant gate, which can be called the "Gate to Heaven". On the right side of the giant gate, there is a remnant hill with jagged stone teeth. There is a "Flying Totem" at the foot of the hill, which is like a natural welcoming "mural" embedded in the green door wall.
