Introduction to Dahuang Kiln: 5,000 meters away from Guoliang Village, it is a kiln niche on a cliff, more than 100 meters high, with a depression of more than 20 meters. The rock wall is light yellow in color and as steep as a knife. At a height of more than 40 meters from the foot of the cliff, there are two rows of wooden prongs nailed into the rock crevices. Each wooden prong is about 1 meter apart. They are arranged up and down and vary in thickness. Some are as thick as an arm, and some are as thick as an egg. There are 38 wooden prongs in total. The root, I don’t know when and how it was planted, is similar to the mystery of the hanging coffin.
