This knight of romance was to experience many adventures before he should return to his native land. Attended by a hundred devoted companions, he set out, but in endeavoring to cross the country of the Heung-nou the whole party were made prisoners and held in captivity for ten long years. Finally, after a bitter experience of desert life, the survivors made their escape, and, with a courage that had outlived their years of thraldom, resumed their search for the vanished tribes. Many western countries were visited in the search, and much strange knowledge was gained. In the end the Yuchi were found in their new home. With them Chang Keen dwelt for a year, but all his efforts to induce them to return were in vain. They were safe in their new land, and did not care to risk encounter with their old foes, even with the Emperor of China for their friend. Finally the adventurous envoy returned to China with two of his companions, the only survivors of the hundred with whom he had set out years before. He had an interesting story to tell of lands and peoples unknown to the Chinese, and wrote an account of his travels and of the geography of the countries he had seen. Chang Keen was subsequently sent on a mission to the western kingdom of Ousun, where he was received with much honor, though the king declined to acknowledge himself a vassal of the ruler of China. From here he sent explorers far to the south and north, bringing back with him fresh information concerning the Asiatic nations. Of the Yuchi later stories are told. They are said to have come into collision with the Parthians, whom they vanquished after a long-continued struggle. They are also credited with having destroyed the kingdom of Bactria, a far-eastern relic of the empire of Alexander the Great. Several centuries later they may have combined with their old foes to form the Huns, who flung themselves in a devastating torrent upon Europe, and eventually became the founders of the modern kingdom of Hungary. _THE "CRIMSON EYEBROWS."_ With the opening of the Christian era a usurper came to the Chinese throne. In the year 1 B.C. the emperor Gaiti died, and Wang Mang, a powerful official, joined with the mother of the dead emperor to seize the power of the state. The friends and officials of Gaiti were ruined and disgraced, and in the year 1 A.D. a boy of nine years was raised to the throne as nominal emperor, under whose shadow Wang Mang ruled supreme. Money was needed for the ambitious upstart, and he obtained it by robbing the graves of former monarchs of the jewels and other valuables buried with them. This, from the Chinese point of view, was a frightful sacrilege, yet the people seem to have quietly submitted to the violation of the imperial tombs.
