ch. 25.

7. The appellation of Hu Yen, mentioned in ch. 39 under the year
637.

8. Wang-tzu Ch`eng-fu, ch. 32, year 607.

9. The mistake is natural enough. Native critics refer to a
work of the Han dynasty, which says: "Ten LI outside the WU gate
[of the city of Wu, now Soochow in Kiangsu] there is a great
mound, raised to commemorate the entertainment of Sun Wu of Ch`i,
who excelled in the art of war, by the King of Wu."

10. "They attached strings to wood to make bows, and sharpened
wood to make arrows. The use of bows and arrows is to keep the
Empire in awe."

11. The son and successor of Ho Lu. He was finally defeated and
overthrown by Kou chien, King of Yueh, in 473 B.C. See post.

12. King Yen of Hsu, a fabulous being, of whom Sun Hsing-yen
says in his preface: "His humanity brought him to destruction."

13. The passage I have put in brackets is omitted in the T`U
SHU, and may be an interpolation. It was known, however to Chang
Shou-chieh of the T`ang dynasty, and appears in the T`AI P`ING YU
LAN.

14. Ts`ao Kung seems to be thinking of the first part of chap.
II, perhaps especially of ss. 8.

15. See chap. XI.

16. On the other hand, it is noteworthy that WU TZU, which is
not in 6 chapters, has 48 assigned to it in the HAN CHIH.
Likewise, the CHUNG YUNG is credited with 49 chapters, though now
only in one only. In the case of very short works, one is
tempted to think that P`IEN might simply mean "leaves."

17. Yeh Shih of the Sung dynasty [1151-1223].

18. He hardly deserves to be bracketed with assassins.

19. See Chapter 7, ss. 27 and Chapter 11, ss. 28.

20. See Chapter 11, ss. 28. Chuan Chu is the abbreviated form
of his name.

21. I.e. Po P`ei. See ante.

22. The nucleus of this work is probably genuine, though large
additions have been made by later hands. Kuan chung died in 645
B.C.

23. See infra, beginning of INTRODUCTION.

24. I do not know what this work, unless it be the last chapter
of another work. Why that chapter should be singled out,
however, is not clear.

25. About 480 B.C.

26. That is, I suppose, the age of Wu Wang and Chou Kung.

27. In the 3rd century B.C.

28. Ssu-ma Jang-chu, whose family name was T`ien, lived in the
latter half of the 6th century B.C., and is also believed to have
written a work on war. See SHIH CHI, ch. 64, and infra at the
beginning of the INTRODUCTION.
