• 王皙 Wang Hsi , also of the Sung dynasty, is decidedly original in some of his interpretations, but much less judicious than Mei Yao-chʽên , and on the whole not a very trustworthy guide. He is fond of comparing his own commentary with that of Tsʽao Kung , but the comparison is not often flattering to him. We learn from Chʽao Kung-wu that Wang Hsi revised the ancient text of Sun Tzǔ , filling up lacunae and correcting mistakes. 110
• 何延錫 Ho Yen-hsi of the Sung dynasty. The personal name of this commentator is given as above by 鄭樵 Chêng Chʽiao in the Tʽung Chih , written about the middle of the twelfth century, but he appears simply as 何氏 Ho Shih in the Yu Hai , and Ma Tuan-lin quotes Chʽao Kung-wu as saying that his personal name is unknown. There seems to be no reason to doubt Chêng Chʽiao’s statement, otherwise I should have been inclined to hazard a guess and identify him with one 何去非 Ho Chʽü-fei , the author of a short treatise on war entitled 備論 , who lived in the latter part of the 11th century. 111 Ho Shih’s commentary, in the words of the Tʽien-i-ko catalogue, 有所裨益 “contains helpful additions” here and there, but is chiefly remarkable for the copious extracts taken, in adapted form, from the dynastic histories and other sources.
