It appears that envoys, at least in Lu, were hereditary in some families, just as other families provided successive generations of ministers. A Lu envoy to Tsin, who carried a very valuable gem- studded girdle with him, had very great pressure put upon him by a covetous Tsin minister who wanted the girdle. The envoy offered to give some silk instead, but he said that not even to save his life would he give up the girdle. The Tsin magnate thought better of it; but it is remarkable how many cases of sordid greed of this kind are recorded, all pointing to the comparative absence of commercial exchanges, or standards of value between the feudal states. Ts'u seems to have thoroughly deserved Yen-tsz's imputations of treachery and roguery. At the great Peace Conference held outside the Sung capital in 546, the Ts'u escort was detected wearing cuirasses underneath their clothing. One of the greatest of the Tsin statesmen, Shuh Hiang (a personal friend of Yen-tsz, Confucius, and Tsz-ch'an) managed diplomatically to keep down the rising indignation of the other powers and representatives present by pooh-poohing the clumsy artifice on the ground that by such treachery Ts'u simply injured her own reputation in the federation to the manifest advantage of Tsin: it did not suit Tsin to continue the struggle with Ts'u just then. Then there was a squabble as to precedence at the same Peace Conference; that is, whether Tsin or Ts'u had the first right to smear lips with the blood of sacrifice: here again Shuh Hiang tactfully gave way, and by his conciliatory conduct succeeded in inducing the federal princes to sign a sort of disarmament agreement. This is one of the numerous instances in which Confucius as an annalist tries to _menager_ the true facts in the interests of orthodoxy. Even the more fully civilized state of Ts'i attempted an act of gross treachery, when in 500 B.C. the ruler of Lu, accompanied by Confucius as his minister in attendance, went to pay his respects. But Confucius was just as sharp as Yen-tsz and Tsz-ch'an, his friends, neighbours, and colleagues: he at once saw through the menacing appearance of the barbarian "dances" (introduced here, again, as a "variety entertainment"), and by his firm behaviour not only saved the person of his prince, but shamed the ruler of Ts'i into disclaiming and disavowing his obsequious fellow- practical jokers. Yen-tsz was actually present at the time, in attendance upon his own marquis; but it is nowhere alleged that he was responsible for the disgraceful manoeuvre. As a result T'si was obliged to restore to Lu several cities and districts wrongfully annexed some years before, and Lu promised to assist Ts'i in her wars. [Illustration: MAP
