When Wu, after a series of bloody wars with Ts'u and Yiieh, was in 473 finally extinguished by the latter power, a portion of the King of Wu's family escaped in boats in an easterly direction. At this time not only was Japan unknown to China under that name, but also quite unheard of under any name whatever. It was not until 150 years later that the powerful states of Yen and Ts'i, which, roughly speaking, divided with them the eastern part of the modern province of Chih Li, the northern part of Shan Tung, and the whole coasts of the Gulf of "Pechelee," began to talk vaguely of some mysterious and beautiful islands lying in the sea to the east. When the First August Emperor had conquered China, he made several tours to the Shan Tung promontory, to the site of the former Yueh capital (modern Kiao Chou), to the treaty-port of Chefoo (where he left an inscription), to the Shan-hai Kwan Pass, and to the neighbourhood of Ningpo. He also had heard rumours of these mysterious islands, and he therefore sent a physician of his staff with a number of young people to make inquiry, and colonize the place if possible. They brought back absurd stories of some monstrous fish that had interfered with their landing, and they reported that these fish could only be frightened away by tattooing the body as the natives did, The people of Wu, who were great fisherfolk and mariners, were also stated to have indulged in universal tattooing because they wished to frighten dangerous fish away. The first mission from Japan, then a congeries of petty states, totally unacquainted with writing or records, came to China in the first century of our era; it was not sent by the central King, but only by one of the island princes. Later embassies from and to Japan disclose the fact that the Japanese themselves had traditions of their descent both from ancient Chinese Emperors and from the founder of Wu, i.e. from the Chou prince who went there in 1200 B.C.; of the medical mission sent by the First August Emperor; of the flight from Wu in 473 B.C. of part of the royal Wu family to Japan; and of other similar matters--all apparently tending to show that the refugees from Wu really did reach Japan; that a very early shipping intercourse had probably existed between Japan, Ts'i, and Wu; and that, in addition to the statements made by later Chinese historians to the effect that the Japanese considered themselves in some way hereditarily connected with Wu, the early Japanese traditions and histories (genuine or concocted) themselves separately repeated the story. One of the later Chinese histories says of Wu: "Part of the king's family escaped and founded the kingdom of Wo" (the ancient name for the Japanese race): the temptation to connect this word with _Wu_ is obvious; but etymology will not tolerate such an identification, either from a Chinese or a Japanese point of view; the etymological "values" are _Ua_ and Gu respectively.
