1. Paper is one of the four great inventions in ancient China, and it has made outstanding contributions to the spread of culture in history. Even today when machine-made paper is prevalent, some traditional handmade paper still reflects its irreplaceable function and radiates a unique brilliance. The ancient paper can still be seen in the ancient paintings and calligraphy that have been handed down.

2. For a long time before the invention of paper, what did people use as a note-taking material? According to the literature and physical data, the earliest people used knotted ropes to record events. Later, inscriptions were engraved on the tortoise shell and animal bones, the so-called "oracle bone inscriptions". After the bronze was produced, inscriptions were cast on bronze ware, that is, "Golden inscriptions" or "Zhongdingwen". After that, the characters are written on the pieces made of bamboo and wood, which are called "bamboo and wood slips", and the thicker bamboo and wood pieces are called "mu". At the same time, some are also written on silk products. Before the pre-Qin period, in addition to the above memoirs, writings carved on stones were also found.

3. It is generally known that paper was invented by Cai Lun in the Eastern Han Dynasty. But archaeological excavations raise questions about this. With the progress of archaeological work along the Northwest Silk Road, many sites and tombs of the Western Han Dynasty have been discovered, among which there is no shortage of paper relics. These right papers are named according to the place where they were unearthed.
