About 1,000 years ago, a Chinese man named Bi Sheng invented movable type printing.
The movable components are cubes made of baked clay.
Each cube is carved with a Chinese character, and these blocks look like the common seals used by Chinese people.
These blocks can be flexibly arranged, combined, and formed into sentences.
When printing, a square iron plate with a frame is used as a base.
When ink is brushed and paper is covered, a neatly composed print is born.
Bi Sheng's invention of movable type printing greatly improved the printing efficiency, allowing the traditional manual transcription to develop into modern batch printing.
Words and pictures spread more quickly and widely throughout the world with the help of movable type printing.
