ly foreigners, but to the officials in the
provinces and prefectures through which the routes passed. Thus the
officials in western China were interested in the trade routes being
brought under direct control, so that the caravans could arrive
regularly and be immune from robbery. Finally, the Chinese government
may well have regarded it as little to its honour to be still paying
dues to the Hsiung-nu and sending princesses to their rulers, now that
China was incomparably wealthier and stronger than at the time when that
policy of appeasement had begun.

The first active step taken was to try, in 133 B.C., to capture the
head of the Hsiung-nu state, who was called a _shan-yue_; but the
_shan-yue_ saw through the plan and escaped. There followed a period of
continuous fighting until 119 B.C. The Chinese made countless attacks,
without lasting success. But the Hsiung-nu were weakened, one sign of
this being that there were dissensions after the death of the _shan-yue_
Chuen-ch'en, and in 127 B.C. his son went over to the Chinese. Finally
the Chinese altered their tactics, advancing in 119 B.C. with a strong
army of cavalry, which suffered enormous losses but inflicted serious
loss on the Hsiung-nu. After that the Hsiung-nu withdrew farther to the
north, and the Chinese settled peasants in the important region of
Kansu.
Meanwhile, in 125 B.C., the famous Chang Ch'ien had returned. He had
been sent in 138 to conclude an alliance with the Yueeh-chih against the
Hsiung-nu. The Yueeh-chih had formerly been neighbours of the Hsiung-nu
as far as the Ala Shan region, but owing to defeat by the Hsiung-nu
their remnants had migrated to western Turkestan. Chang Ch'ien had
followed them. Politically he had had no success, but he brought back
accurate information about the countries in the far west, concerning
which nothing had been known beyond the vague reports of merchants. Now
it was learnt whence the foreign goods came and whither the Chinese
goods went. Chang Ch'ien's reports (which are one of the principal
sources for the history of central Asia at that remote time)
strengthened the desire to enter into direct and assured commercial
relations with those distant countries. The government evidently thought
of getting this commerce into its own hands. The way to do this was to
impose "tribute" on the countries concerned. The idea
