Li Zhi, hero of the “Biography of Li Wen-Ling” written by Yuan Zhong-Dao, was a controversial figure during his lifetime or after his death. People have hailed him as Li Erh (founder of Taoism), or a high-minded recluse. To those who disliked him, Li was a non-conformist or a demonic character. To be sure, one must consider the contradictory nature in the critical evaluation of Li, and approach it from historical and biographical grounds. Yuan Zhong-Dao, the author in question here, was one of the outstanding figures of the ‘Gong-An’ School in the late Ming period. His literary reputation was considered inferior to that of his older brother Yuan Hong-Dao, and so people have only researched into the genres of diary and travelogue pertaining to Li’s writings. In fact, many pieces of his biographical accounts, as is with the ‘The Biography of Li Wen-Ling’, are worthy of scholarly discussion. Although critics have cited the Biography of Li only as a secondary history record, Li Zhi, Yuan’s teacher, highly regarded this biography as an important work, combining historiographical accuracy and literary techniques. In Yuan’s biographical world, Li Wen-Ling’s extraordinary personality is presented in a special light. With a view to giving a full appreciation of the work, I would like to approach it from the three following aspects: 1) a discussion of the main themes focusing on the idea of heterodoxy or nonconformity; 2) chapter division dealing with literary art of description, commentary and character sketch, and 3) rhetoric skills expressed in the use of figurative language and dialogues.
