 However, this technology was abandoned in favour of clay movable types due to the presence of wood grains and the unevenness of the wooden type after being soaked in ink.In 1298, Wang Zhen (王祯/王禎), a Yuan dynasty governmental official of Jingde County, Anhui Province, China, re-invented a method of making movable wooden types.He made more than 30,000 wooden movable types and printed 100 copies of "Records of Jingde County" (《旌德縣志》), a book of more than 60,000 Chinese characters.
