A Chinese named Bi Sheng invented movable type
print around 1,000 years ago. The movable components
are cubes made of baked clay. Characters were carved on each piece of clay,
which looked like the seals widely used in China. The movable components could be arranged freely
to form different vocabularies and sentences. They were fixed on an iron plate with frames
in certain sequence. Then ink was painted and a piece of paper was laid down. A printed sheet was created this way. This technique improved the efficiency of
printing and transformed traditional transcription into modern printing. Scripts and paintings spread widely in the world
with the help of yìn shuā.
