Qingshan is a small town in the southern suburbs of Pu 'an County, Southwest Guizhou, located at the junction of Xingyi, Xingren and Panxian. 1980 10, the archaeological team of Guizhou Provincial Museum excavated the ancient site of Tonggushan in the northeast corner of Qingshan Town, and unearthed more than 300 precious cultural relics, including stone tools, bone implements, bronzes, ironware, pottery and China coins 1000, among which Fan Tao was first seen in Guizhou. In particular, the shape and ornamentation of "one-character bronze sword" are obviously different from the surrounding cultures of Yunnan, Pakistan, Chu and South Vietnam, and even more different from the Central Plains culture, with a unique Yelang style. Fan Tao's discovery shows that during the Western Han Dynasty, exquisite bronzes and ironware were made in the border areas of Guizhou.
In ancient times, Pu 'an belonged to Yelang State, which was undoubtedly the long-term direct or indirect ruling area of Yelang State. There are always different opinions about the location of the first city of Yelang Kingdom, but there are a lot of historical data that its central area is located in the middle and upper reaches of Beipanjiang River, which is not too far. Qingshan is just in the middle and upper reaches of the north-south Panjiang watershed, less than a hundred miles away from the river. Legend has it that "Qingshan Bazi" was called "Yelangba" in ancient times, and Yelangwang made a fortune here. In ancient times, Yelangba was very prosperous. According to legend, there are 99 villages, 99 huts or plates on the hills near the villages, 99 mirror-clear ponds and 99 weathertight caves. The existing landscape is similar to the legend, just under the ground of Qingshan Town, 5 kilometers square. There are Xingxiu Cave, Guanyin Cave, Xiangkeng Cave, Yan Ying Cave, Hualongtan and Gao Man Longtan named after the scenery, Sanmen Cave, Jiuceng Cave and Ganlong Cave named after the shape, Bailongtan, Heilongtan and Qinglongtan named after the water color, Lijiatan and Yangjiatan named after the place names, and Qixingtang and Ximatang. There are pools in the cave, pools in the pool, pools in the pool, and holes in the pool, which are connected in series into a huge maze. These natural living conditions provided Yelang's ancestors with a unique place to farm, smelt and fish in peacetime and defend themselves in wartime.
From 1980s to 1990s, the ancient Yelangguo village sites around Bazi in Qingshan Town were excavated, and 1 1 contiguous sites have been excavated. According to archaeologists in the province, there are 19 Yelang Age sites discovered so far in Guizhou Province, and Qingshan Town accounts for 1 1, which is really rare in Guizhou.
