doubted whether the story referred to Ts'in or to the Emperor; or might well have decided to incorporate it with orthodox history, as a strengthening factor in support of the theory of one single and indivisible imperial dignity; just as, again, in the seventh century and eighth century A.D., the Japanese manipulators of their traditional history incorporated hundreds, not to say thousands of Chinese historical facts and speeches, and worked them into their own historical episodes and into their own emperors' mouths, for the honour and glory of Dai Nippon (Great Japan). After the death of the Second Protector in 628 B.C., there was a continuous struggle between Tsin and Ts'in on the one hand, and between Tsin and Ts'u on the other. Meanwhile Ts'i had all its own work cut out in order to keep the Tartars off the right bank of the Yellow River in its lower course, and in order to protect the orthodox Chinese states, Lu, Sung, Wei, etc., from their attacks; but Ts'i never again after this date put in a formal claim to be Protector, although in 610 she led a coalition of princes against an offending member, and thus practically acted as Protector. In addition to the Chinese adviser at the disposal of Ts'in, in the year 626 the King (or a king) of the Tartars supplied Duke Muh with a very able Tartar adviser of Tsin descent; i.e. his ancestors had in past times migrated to Tartarland, though he himself still "spoke the Tsin dialect," and must have had considerable literary capacity, as he was an author. Ts'in was now, in addition to being, if only informally, a federal Chinese state, also supreme suzerain over all the Tartar principalities within reach; well supplied, moreover, with expert advisers for both classes of work. All this is important in view of the pre- eminency of Ts'in when the time came, 400 years later, to abolish the meticulous feudal system altogether. CHAPTER XIV MORE ON PROTECTORS
