printing techniques during the Yuan Dynasty (1271---386). The greatest achievement in the
printing tech-niques was Wang Zhen's innovation in the of the
technology of wooden movable type. He hired people to carve movable wooden types and then
designed a revolving typesetting plate to store the movable types according to the order
