A large number of silk books and two volumes of medical slips were found in Mawangdui Han Tomb, all of which came from rectangular lacquer boxes in the east box of Tomb No.3. Most of the silk books were written on a whole piece of silk book with a width of 48 cm and folded into rectangles. A few of them were written on half a piece of 24 cm wide silk and rolled up with wooden strips. When they were excavated, they were seriously damaged. After sorting, I know that there are 28 pieces. Except Zhouyi and Laozi, most of them are ancient lost books, and there are two ancient maps. This is an important discovery recorded in ancient books in China archaeology.

There are 200 pieces of bamboo slips in two volumes, one of which is similar to Huangdi Neijing, which is about the way of keeping in good health, and the other is about the art in the room.

Among them, the A and B versions of Laozi are the oldest versions we have seen so far. The discovery of Wuxing Zhan is the oldest astronomical document discovered by China. Fifty-two Prescriptions for Diseases is the oldest medical book found in China. It is expected that the collection of bamboo slips and silk books from Mawangdui Han Tomb in Changsha will be published in 20 12, including all the contents.
