The Invention of Paper PPT, Part 2: Entering the Text

As early as thousands of years ago, our ancestors created writing. But there was no paper at that time. If you wanted to record something, you would use a knife to carve the words on tortoise shells and animal bones, or cast the words on bronze vessels. Later, people carved characters on bamboo and wood chips. These bamboo and wood pieces were tied together with ropes to form a book. However, this kind of book is very bulky and inconvenient to read, carry and store. In ancient times, "learned and rich with five carts" was used to describe a person with high knowledge, because when he had many books, he needed a cart to pull them. Later, when silk was woven into silk fabrics, it was possible to write on the silk fabrics. Silk is lighter than bamboo and wood chips, but it is too expensive and only a few people can use it, so it cannot be widely used.

When people used silkworm cocoons to make silk floss, they discovered that a layer of thin sheets would be left on the bamboo mat holding the silkworm cocoons, which could be used for writing. Archaeologists have discovered that people already knew how to use hemp to make paper more than two thousand years ago during the Western Han Dynasty. But hemp paper is rough and difficult to write on.

About 1,900 years ago in the Eastern Han Dynasty, a man named Cai Lun absorbed people's long-term accumulated experience and improved papermaking technology. He chopped or cut bark, hemp heads, straw, rags and other raw materials, soaked them in water and pounded them into pulp; then he took the pulp out and dried it in the sun, and it became a kind of paper that is both light and easy to use. The raw materials for paper made by this method are easy to obtain, can be produced in large quantities, are cheap, and can meet the needs of most people, so this papermaking method has been passed down.
