The Chinese were the real inventor of printing. Centuries ago they carved messages on stone and then sprinkled (撒) sooty(粉末状的) dust over the stone carving. When they put a small piece of paper over the stone and rubbed the paper, the sooty lines were reproduced on it. Some of these first printed papers have been preserved; the oldest ones known to exist are more than one thousand years old.
Printing with carved stone blocks was the only kind of printing known for centuries. Then, about eight hundred years ago, a Chinese printer, Bi Sheng, had a clever idea. Instead of carving a whole message on a single big block of wood or stone, he formed separate Chinese words or characters out of bits of clay(粘土). By fitting the clay pieces together in rows in a box, he could print just as before. But when he finished, he could keep all the separate pieces of clay and use them again.
Bi Sheng’s movable type was a great step forward, but his method was not generally adopted. Movable type did not come into use in Europe until it was invented there centuries later. The Europeans had been totally ignorant(无知的) of the printing traditions of the Chinese.
