Recently, Huishan mining area in Qiaoshi Town of Guiyang County, with green planting, winding roads circling the mountains and clear streams flowing down the mountains, has formed a beautiful ecological picture. Huishan is rich in mineral resources, but the environment is increasingly damaged because of years of mining. In recent years, Guiyang County has steadily promoted the ecological protection and restoration of mines, and implemented the "green mountains" project, so that the mine restoration has achieved initial results. Now bare hills are covered with green clothes, and green patches are coming back to people's vision.
