Restoration work is underway on what is reportedly the largest-ever bronze mask to be unearthed in China’s Sanxingdui ruins. The relic is believed to be thousands of years old, dating from the Shu Kingdom period. Located in Sichuan province, the archeological site was first discovered in the late 1920s. New relics have been found at the ruins’ No.3 and No.8 ritual pits, which the research team began excavating in October 2020.
