CHIN-SUNG RELATIONS BEFORE II42 233

even the Chin respected the status differ-
ence of generations.
Note also that the name of their new fief was a perfectly neutral one and
not derogatory, as their former titles had been. T'ien-shui was a commandery
at the upper course of the Wei River in the eastern part of what is now Kansu
Province. A few months later Ch'in-tsung was given the emoluments due his
ducal rank. After the treaty had been concluded, the male relatives of the two
emperors who were still in Chin captivity were accorded emoluments, a
privilege that was extended in 1150 to the female descendants of the former
Sung emperors. In other words, the Chin treated their captives as hostages
who could always be used to bring pressure on the Sung. The death of Ch'in-
tsung in 1156, however, deprived the Chin of their principal hostage on
whom they could rely to prevent the Sung from breaking the peace treaty.
This treaty of 1142, which was to regulate Sung-Chin relations for almost
twenty years, was the result of protracted negotiations. The Chin had the
advantage of being able to use the return to the Sung of the coffins of Hui-
tsung, his empress, and the emperor's mother as a bargaining chip. In
addition they kept up the military pressure by repeatedly sending troops into
the territory south of the Yellow River and in 1140 again conquered the
whole of Honan and Shensi, which had been returned to Sung control early in
1139 after the conclusion of a preliminary peace. But the conclusion of a
peace treaty would not have been possible if the revanchists had remained in
power at Hangchou, where the Sung had finally established their capital in
1138.
The elimination of Yiieh Fei, the most successful and popular of the
Sung generals, by his adversary Ch'in Kuei opened the way toward a final
agreement. In 1141 Yiieh Fei was ignominiously put to death in his prison, a
foul deed that made the advocate of coexistence, Ch'in Kuei, forever a bete
noire in Chinese history.
Almost at the same time, negotiations between Sung and Chin were
initiated. These were extremely involved and protracted. It seems that the
Chin side, through the commander Wan-yen Tsung-pi, signaled to the Sung
that a peace could be obtained by agreeing to make the Huai River the border
between the two states. This was in October 1141. Wan-yen Tsung-pi was
the fourth son of A-ku-ta and had been entrusted with operations in central
China. Two months later the Sung agreed in principle. Extracts from state
letters of both sides have survived in Sung sources; their dates range from
October 1141 to October 1142. But the texts of the treaty
itself,
or, more
correctly, the oath-letters of Chin and Sung, have not survived. What we
have is an abbreviated version of the Sung oath submitted already by the end
of 1141. The terms of peace were harsh. The Sung agreed to have the middle
course of the Huai River as a border, which meant that the whole of the
