Xinhuang mercury mine industrial heritage site group is located in the hotel pond in the west of the county. Mining began in Qin and Han dynasties, and it has a history of more than 2000 years. In the middle of Qing Dynasty, mercury was refined. After liberation, the local people's government cleaned up and rectified the mines, and constantly carried out technological innovation and transformation, which made the mining industry flourish and became one of the three "mercury capitals" in China. In April 2003, due to the exhaustion of resources, production stopped and closed down.

According to reports, there are many industrial and cultural remains with historical value, technical value and scientific research value in the former site of mercury mine. There are a lot of relics left in the mine, such as stone ladders, tunnels, trenches, markers, pillars and roadways excavated by miners for hundreds of years, as well as a set of unique and advanced technologies formed in mining, mineral processing and smelting, which are the epitome of the history of mercury mines in China and precious physical materials for studying the mining history of mercury mines in China.
