Mawangdui Han Tomb has never been stolen for more than 2,000 years and is well preserved. As a result, a large number of cultural relics have been unearthed, especially the immortal corpse of the magical woman unearthed from Tomb No. 1 and the large number of silk documents unearthed from Tomb No. 3, which provided abundant information for the historical textual research of the early Western Han Dynasty and shocked the world. When unearthed, tomb No. 1 was sealed with white plaster and mud, so the female corpse remained intact after 2,000 years. When it was discovered, some gases erupted and burned. However, due to the lack of timely collection of gases and the lack of specific ingredients, it became a mystery that the female wet corpse remained intact for thousands of years.
