Daoyun Building is located in Nanlian Village, Sanrao Town, Raoping County, Chaozhou City, Guangdong Province. Built in the late Ming and early Qing dynasties, it has a history of more than 400 years. It is the largest Hakka earth building discovered in China so far, and it is also the largest octagonal earth building discovered in China so far. The earth building looks very broken, the crack can reach in, and one wall collapses. , and suddenly turned into a narrower village, the village's low house, low trees, how can support the two buses. Driving along the dense forest road, I thought we were going to the halfway up the mountain to see the circular earth building. At that time, we had already filled up a lot of pictures: clear creek is a earthen building like a missile base. The circles are surrounded by verdant mountains. It is in a village of yellow mud bricks.
