The Terracotta Warriors are one of those things you won’t be able to comprehend the scope of, or the work that went into it until you have seen them in person. There are thousands of DIFFERENT looking warriors. In the middle of all this are tombs. Researchers found extreme high levels of mercury and believe that mercury rivers surround the tombs. This is the reason why they haven’t bothered to excavate it from fears of mercury poisoning.
There isn’t that much to say apart from come and view them yourself. You won’t be dissapointed!
