Summary to the text

　　As a result of the invention of paper, much is known about China history. However, in other parts of the world, much of the history is completely unknown. The Chinese people used different kinds of ways to keep records. Then they began to write on a kind of paper made from silk - But it was too expensive . So people developed a kind of paper, made from the fibers of plants, which was as soft and light as silk but cheaper.
