This is a bronze human head (or bronze mask) in Sanxingdui, one of the representative cultural relics of ancient Chinese Shu culture. The No. 2 sacrificial pit unearthed in 1986 at the Sanxingdui site in Guanghan, Sichuan, belongs to the late Shang Dynasty (about 3200 years ago). These bronze human heads have unique shapes, such as exaggerated apricot eyes, wide mouths and large ears. Some are even painted with black eyebrows and vermilion lips. Scholars speculate that they may have been used in religious or sacrificial ceremonies, representing gods or ancestors, and may have been mounted on wooden supports or totem poles, or even clothed in clothing.

The golden mask is a golden artifact unearthed from the 5th sacrificial pit in the Sanxingdui site's sacrificial area. After testing, its gold content is about 85%, silver content is about 13% to 14%, and there are other impurities.

The Sanxingdui Site is an ancient Shu culture site dating back approximately 5000 to 3000 years, during the late Neolithic period. In January 1998, it was announced by the State Council as a "National Key Cultural Relics Protection Unit" and has now been included in the list of World Cultural Heritage Key Protection Units. At the Sanxingdui site, many bronze human masks were unearthed, totaling more than 20 earth human masks, divided into three types: large, medium, and small. These bronze mask groups, represented by the vertical eye masks, are one of the most distinctive and spiritually cultural relics in Sanxingdui. They are the earliest and largest mask groups unearthed in China.
