For a long time, Wa people have lived in the same area as Han, Dai and Lahu people, and economic and cultural exchanges have promoted each other's development. After the middle of the Ming Dynasty, a large number of Han miners successively entered the Awashan area to mine silver and settled here. At the beginning of Qing Dynasty, more poor working people of Han nationality came here. There are as many as 20,000 or 30,000 miners in the Maolong Silver Factory opened in Shang Xian, Wu Shiping, a tribe of Banhong and Banlao.
