Chronology of Bamboo Books, also known as Chronology of Jizhong, is a part of bamboo books in Jizhong. It was unearthed in the fifth year of Xianning in the Western Jin Dynasty (279), and some of it was burned by grave robbers.
After the government found it, it timely protected and sorted it out, and convened top scholars from North Korea to study it. Unfortunately, due to the long and frequent wars, both the original and the copy were lost.
