About papermaking. Emergency, emergency, emergency

There is a clear record in the history book "The Book of the Later Han Dynasty": "Since ancient times, book contracts have been compiled with bamboo slips, and those who use silk are called paper. Expensive and simple, inconvenient for people. Lennart created this idea, using bark, hemp head, our cloth and fishing nets as paper. It was played in the first year of Yuanxing (AD 105). The emperor is good at his abilities and does not have to worry about it, so the world is salty and called' Cai Hou Paper'. " Based on the significance and position of the Book of the Later Han Dynasty at that time and in history, later generations think that Cai Lun invented papermaking in the Eastern Han Dynasty.

Due to new archaeological discoveries, the traditional view of "Cai Lun papermaking" has caused controversy not only in China, but also among many experts in papermaking history in Asia.

1957 baqiao paper unearthed in Shaanxi, 1974 Jinguan paper unearthed in the former site of the Han Pavilion in Juyan, Gansu, 1978 Zhongyan paper unearthed in the Western Han kiln in Zhongyan Village, Fufeng, Shaanxi. According to archaeological experts' research and dating, these papers were confirmed to be from the early to the late Western Han Dynasty. Pan Jixing, a researcher at the Institute of Natural Science History of Chinese Academy of Sciences, pointed out that China had paper in the Western Han Dynasty before Cai Lun. Cai Lun should not be the inventor of papermaking, and the history of papermaking in China should be at least two or three centuries earlier.
