印刷术 Movable type the system of printing and typography that uses movable components to reproduce the elements of a document (usually individual letters or punctuation). The first known movable type system was invented in China by Bi Sheng out of ceramic between 1041 and 1048 AD. Metal movable type was first invented in Korea during the Goryeo Dynasty (around 1230). This led to the printing of the Jikji in 1377 - today the world's oldest extant movable metal print book.
