In ancient China, the silk cocoons of the working people and above were used to draw silk and weave silk. After finishing the floc, the bamboo mat will be left some residual floc.

When the number of drift floc more, bamboo mat on the residual floc will be accumulated into a layer of thin fiber, after drying off, can be used for writing.

3、Gunpowder

4、The printing press

The earliest engraving found so far is a single page version of the douroni sutra in Indian Sanskrit, printed on linen paper, published between 650 and 670 years ago, and unearthed in a tang dynasty tomb near xi 'an in 1974.

In 1966, archaeologists in South Korea discovered a miniature version of the doloni buddhist sutra, which contained the text of the zuren script issued by empress wu zetian of the tang dynasty (C. 690-705).

Scholars determined that the sutra did not date back to 704 and was later preserved in a stupa built during the unification of silla in 751.

However, the earliest known printed book of an average size was the diamond sutra published during the tang dynasty (618-907).

The scroll, which is 5.18 meters (17 feet) long and in scroll format, dates back to April 15 (868), the ninth lunar month of emperor yizong's reign.

The accounts of scholars Joseph Needham and Tsien tsuen-hsuin show that the calligraphy and carving techniques of the tang dynasty diamond sutra were far more advanced and sophisticated than the single-page Indian version of the doloni sutra,

which was printed earlier. In addition, the two oldest printed lunar calendar dates are 877 and 882, when they were discovered in dunhuang.
