Bi Sheng
Ceramic and wooden movable type were invented in the Northern Song dynasty around the year 1041 by the commoner Bi Sheng. Metal movable type also appeared in the Southern Song dynasty. The earliest extant book printed using movable type is the "Auspicious Tantra of All-Reaching Union", printed in Western Xia c. 1139–1193. Metal movable type was used in the Song, Jin, and Yuan dynasties for printing banknotes. The invention of movable type did not have an immediate effect on woodblock printing and it never supplanted it in East Asia.
