In mining of Changsha Mawangdui fire tomb, on the night when the coffin was opened, the Museum of Hunan province did not lit up the sky. Archaeological expert Bai Rongjin said he was unclear of the situation inside, the surrounding provincial leaders gradually dispersed. But this was not the case in practice, only Bai Rongjin who cut the silk wrap knew himself. In this silk wrap, Bai Rongjin clearly felt a body very elastic. His experience told him that the coffin mummy preserved like a man just died soon.
