To take a few instances. In 559 the ruler of Wei had severely beaten his court music-master for failing to teach a concubine how to play the lute. One day the prince invited to dinner some statesmen, the father of one of whom had taken offence at the prince's rudeness; and he ordered the same musician to strike up the last stanza of a certain ode hinting at treason, which the malicious performer did in such a way as to give further offence to the father through his son, and to bring about the dethronement of the indiscreet prince. It gives us confidence in the truth of these anecdotes when we find that K'ü-pêh-yüh was consulted by the offended father as to what course he ought to pursue. This Wei statesman, who has already been twice mentioned in connection with other matters, met Ki-chah of Wu when the latter visited that state in 544, and he was also an admired senior acquaintance of Confucius himself, whom he twice lodged at his house for many months. Three chapters of the "Book" still remain, after Confucius' manipulations of it, to prove how Wei was first enfeoffed by the Duke of Chou, and one of the Odes actually sings the praises of a Ts'i princess who married the prince of Wei in 753 B.C. Thus we see that the ancient classics are intertwined and mutually corroborative. When the Second Protector (the last of the four Tartar-born brothers to succeed to the Tsin throne) was on his wanderings in 644 B.C., the Marquess of Ts'i gave him a daughter, of whom he became so enamoured that he seemed to be neglecting his political chances amid the pleasures of a foreign country, instead of endeavouring to regain his rightful throne at home. This princess first of all quoted an ode from the group treating of CHÊNG affairs, and secondly cited an apt saying from what she "had heard" the great Ts'i philosopher Kwan-tsz had said, her object being to promote her lively husband's political interests. This all took place a few years after Kwan-tsz's death, and 200 years after the founding of CHÊNG state, and is therefore indirect confirmation of the fact that Kwan-tsz was already a well-known authority, and that contemporary affairs were usually "sung of" in all the orthodox states.
