much booty. Toward the end of 903, A-pao-chi turned his attention to Lu-
lung Province, raiding the frontier districts north of present-day Peking. In
the autumn of that year he was elected
yii-yiieh,
commander in
chief.
He was
still only thirty-one.
His campaigns continued without a break. In 904, 905, and 907 A-pao-
chi mounted campaigns in the north against the Black Cart tribe of the
Shih-wei, and in 906 there were two separate attacks on the Hsi. But his
main attention was now focused on the Chinese border, where he was
increasingly embroiled with the tough frontier forces of Liu Jen-kung, the
governor of Lu-lung. In
905

A-pao-chi negotiated a peace settlement with
his far more formidable neighbor Li K'o-yung, the Sha-t'o ruler of Ho-tung
and a major contender for power in northern China. At the head of a force
of seventy thousand Khitan and tribal cavalry, A-pao-chi met with Li at
Yiin-chou (present-day Ta-t'ung), where they swore brotherhood, symboli-
cally exchanging their gowns and horses. Li K'o-yung was, of course,
anxious to preserve his northern border and also to enter into a military
alliance that would stand him in good stead in his ongoing struggle with
Chu Wen; A-pao-chi sought Li K'o-yung's neutrality while he dealt with
Lu-lung. The treaty shows that A-pao-chi was by now a major force to be
reckoned with, his personal standing eclipsing that of the khaghan, his
nominal ruler. In the eyes of the border Chinese at least, he was already the
leader of the Khitan people.
Meanwhile, hostilities continued on the border of Lu-lung, which was
raided each year from 903 to 907. In one of these cross-border raids an
adopted son of the governor, Liu Jen-kung, was captured. Liu, however,
retaliated by crossing the border each autumn to burn off the grasslands,
thereby denying the Khitan grazing for their herds. On one of these raids
they even took captive a brother of A-pao-chi's wife. These counterraids
caused great hardship, loss of livestock, and famine among the Khitan, so
that the weak khaghan Hen-te-chin was reduced to bribing Liu Jen-kung to
leave the Khitan pastures intact by giving him large numbers of horses. In
907 Hen-te-chin came up for reelection as khaghan. The tribal chieftains,
shamed by his passive response to Liu Jen-kung, deposed him and elected A-
pao-chi as khaghan in his place.

Men, 266, pp. 8676—9. Ssu-ma K'uang's critical note (k'ao-i)
cites early sources, since lost, in support of both dates.

886.
Hsueh Chii-cheng, Chiu Wu-tai shih, 137, pp. 1827-8, says that A-pao-chi succeeded in the
normal way by election. LS, 1, p. 2, however, gives a quite different account, according to which
Hen-te-chin died ac the end of 906, whereupon the Khitan leaders who had received his deathbed
injunction appointed A-pao-chi in his place. However, this must be a falsification. Hen-te-chin
