Bamboo formed the earliest ties with Chinese characters, which can be traced back to the New Stone Age 6,000 years ago. The pictographic symbol of "bamboo" was found on the potteries unearthed in the Yangshao cultural relics of Banpo Village, Xi'an in 1954, and the symbol was also discovered in oracle bone inscriptions and inscriptions on ancient bronze objects. During the period from the Warring States Period (475-221 BC) to the Jin Dynasty (265-420 AD), the people wrote on "bamboo slips." Many of the earliest Chinese historical documents, such as the Book of History, The Book of Rites and Analects of Confucius, were recorded on such material，making great contributions to the development of Chinese culture.
