The original text was interred with King Xiang of Wei (died 296 BC) and re-discovered nearly six centuries later in 281 AD (Western Jin dynasty) in the Jizhong discovery. For this reason, the chronicle survived the burning of the books by Emperor Qin Shi Huang. Other texts recovered from the same tomb included "Guoyu", "I Ching", and the "Tale of King Mu". They were written on bamboo slips, the usual writing material of the Warring States period, and it is from this that the name of the text derives. The strips were arranged in order and transcribed by court scholars, who identified the work as the state chronicle of Wei. According to Du Yu, who saw the original strips, the text began with the Xia dynasty, and used a series of different pre-Han calendars. However, later indirect reports state that it began with the Yellow Emperor. This version, consisting of 13 scrolls, was lost during the Song dynasty.
