• 陳皡 Chʽên Hao appears to have been a contemporary of Tu Mu . Chʽao Kung-wu says that he was impelled to write a new commentary on Sun Tzǔ because Tsʽao Kung’s on the one hand was too obscure and subtle, and that of Tu Mu on the other too long-winded and diffuse. 105 Ou-yang Hsiu , writing in the middle of the 11th century, calls Tsʽao Kung , Tu Mu and Chʽên Hao the three chief commentators on Sun Tzǔ ( 三家 ), and observes that Chʽên Hao is continually attacking Tu Mu’s shortcomings. His commentary, though not lacking in merit, must rank below those of his predecessors.
• 賈林 Chia Lin is known to have lived under the Tʽang dynasty, for his commentary on Sun Tzǔ is mentioned in the 唐書 and was afterwards republished by 紀燮 Chi Hsieh of the same dynasty together with those of Mêng Shih and Tu Yu . 106 It is of somewhat scanty texture, and in point of quality, too, perhaps the least valuable of the eleven.
