Jiangling County
The Zhangjiashan Han bamboo texts are ancient Han Dynasty Chinese written works dated 196–186 BC. They were discovered in 1983 by archaeologists excavating tomb no. 247 at Mount Zhangjia () of Jiangling County, Hubei Province (near modern Jingzhou). The tomb was built for an early Western Han era official who had died in 186 BC. The texts were written on traditional bamboo slips connected by cords into rolled scrolls. The written works included legal case precedents, literature on medicine including "Book on Vessels", mathematics, military strategy, and a calendar with dates ranging from 202 BC to 186 BC.
