A Chinese Biographical Dictionary/Chêng Ch'ien
266 Chêng Ch'ien 鄭虔. 8th cent. A.D. A poet and landscape-painter of the T'ang dynasty, famous for having illustrated his own poems. Being unable to procure paper to write upon, he used persimmon-leaves; yet he rose under the Emperor Hsüan Tsung, A.D. 713—756, to be a Doctor in the Imperial Academy. In consequence of certain published notes on contemporary events, he was accused of tampering with the dynastic history, and was banished for ten years. On his return, he withdrew a large portion of these from circulation. Popularly known as 鄭廣文.
