Western Han timber-chambered Tombs in Laoguan Mountain, Chengdu

In Jinniu District of Chengdu City, Sichuan Province, more than 50 inscribed wooden tablets, four loom models made of bamboo and wood and more than 920 bamboo strips have been unearthed. The 920 bamboo strips make up nine medical classics and maybe the classic books of the Bian Que (407 - 310 BC) School that have been lost for a long time. The loom models have important value for the study on Chinese spinning history. The earliest and most well-preserved medical model of the human body showing acupuncture points has also been discovered, which is important for the study of the development of traditional Chinese medicine.
