Archaeologists worry that the tomb of China's first emperor contains deadly booby traps. An ancient Chinese historian wrote that the tomb is filled with mercury and crossbows ready to fire. A 2020 study found that mercury concentrations around the tomb are higher than to be expected. Ancient Chinese historian Sima Qian wrote an account around 100 years after the emperor's death about possible booby traps inside the tomb. The terracotta army and Qin Shi Huang's tomb complex are designated as UNESCO World Heritage Sites and remain some of the most significant archaeological discoveries in history.
