commentator is given as above by Cheng Ch’iao in the _Tung Chih_,
written about the middle of the twelfth century, but he appears simply
as Ho Shih in the _Yu Hai_, and Ma Tuan-lin quotes Ch’ao Kung-wu as
saying that his personal name is unknown. There seems to be no reason
to doubt Cheng Ch’iao’s statement, otherwise I should have been
inclined to hazard a guess and identify him with one Ho Ch’u-fei, the
author of a short treatise on war, who lived in the latter part of the
11th century. Ho Shih’s commentary, in the words of the _T’ien-i-ko_
catalogue, "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.
