Bamboo slips are bamboo pieces used for writing in ancient China. According to archaeological findings, the history of ancient people writing with bamboo slips can be traced back to the Shang Dynasty, and almost appeared with Oracle Bone Inscriptions. People in Shang dynasty used bamboo slips and wooden slips, and then made them into books with ropes for people to write.
Bamboo slips can be used as ancient writing materials, mainly because the raw materials are cheap, bamboo is distributed all over China, with short growth cycle and easy preservation, which can replace tortoise shells and animal bones that are hard to obtain.
In ancient times, making bamboo slips required six steps: cutting, drying, writing, drilling and editing. When writing, each bamboo slip writes one line, and then all the bamboo slips in an article are combined, which is called "bamboo slips". Before the maturity and popularization of papermaking, bamboo slips were always people's writing materials, and they were not ordered to be abolished until the end of the Eastern Jin Dynasty. It can be said that bamboo slips have made great contributions to the preservation and spread of China culture, so many idioms related to bamboo slips have appeared in later generations.

The idiom "Qing" refers to bamboo slips, "history" refers to history or history books, and "Qing history" is the history books recorded on bamboo slips.
