Buried deep under a hill in central China, surrounded by an underground moat of poisonous mercury, lies an entombed emperor who's been undisturbed for more than two millennia. The tomb holds the secrets of China's first emperor, Qin Shi Huang, who died on September 10, 210 B.C.
The answers to a number of historical mysteries may lie buried inside that tomb, but whether modern people will ever see inside this mausoleum depends not just on the Chinese government, but on science.
