CHAPTER II _CLASSICAL AND GENERAL LITERATURE_ The classical scholarship of the Tang dynasty was neither very original nor very profound. It is true that the second Emperor founded a College of Learning, but its members were content to continue the traditions of the Hans, and comparatively little was achieved in the line of independent research. Foremost among the names in the above College stands that of LU YÜAN-LANG (550-625). He had been Imperial Librarian under the preceding dynasty, and later on distinguished himself by his defence of Confucianism against both Buddhist and Taoist attacks. He published a valuable work on the explanations of terms and phrases in the Classics and in Taoist writers. Scarcely less eminent as a scholar was WEI CHÊNG (581-643), who also gained great reputation as a military commander. He was appointed President of the Commission for drawing up the history of the previous dynasty, and he was, in addition, a poet of no mean order. At his death the Emperor said, “You may use copper as a mirror for the person; you may use the past as a mirror for politics; and you may use man as a mirror to guide one’s judgment in ordinary affairs. These three mirrors I have always carefully cherished; but now that Wei Chêng is gone, I have lost one of them.” Another well-known scholar is YEN SHIH-KU (579-645). He was employed upon a recension of the Classics, and also upon a new and annotated edition of the history of the Han dynasty; but his exegesis in the former case caused dissatisfaction, and he was ordered to a provincial post. Although nominally reinstated before this degradation took effect, his ambition was so far wounded that he ceased to be the same man. He lived henceforth a retired and simple life. LI PO-YAO (565-648) was so sickly a child, and swallowed so much medicine, that his grandmother insisted on naming him Po-yao = Pharmacopœia, while his precocious cleverness earned for him the sobriquet of the Prodigy. Entering upon a public career, he neglected his work for gaming and drink, and after a short spell of office he retired. Later on he rose once more, and completed the History of the Northern Ch‘i Dynasty. A descendant of Confucius in the thirty-second degree, and a distinguished scholar and public functionary, was K‘UNG YING-TA (574-648). He wrote a commentary on the Book of Odes, and is credited with certain portions of the History of the Sui Dynasty. Besides this, he is responsible for comments and glosses on the Great Learning and on the Doctrine of the Mean.
