Confucius' friends that this disciple on taking office should send for Confucius himself, who really wished to be employed in Lu again. Meanwhile Confucius decided to visit the orthodox state of Ts'ai (imperial clan), lying to the south of Che'n: the capital of this state had been originally a town on the upper waters of the Hwai River, right in the heart of modern Ho Nan province; but, under stress of the Tsin and T'su wars, it had twice moved its chief city eastwards, and owing to a Ts'u invasion, it was now (491) on the main Hwai River in modern An Hwei province, and was at the moment under the political influence of Wu; it is not clear, however, whether Confucius visited the old or the new capital. After a year's stay here, Confucius went further westwards to a certain Ts'u town (near Nan-yang Fu in Ho Nan), passing, on his way, near the place in which Lao-tsz was born. He soon returned to Ts'ai, where he stayed three years. It will be observed that ever since 700 B.C. it had been the deliberate policy of Ts'u to annex or overshadow as many of the orthodox states as possible, so that Ts'u's undoubtedly high literary output, in later years, is easily accounted for: in other words, Ts'u's northern population was now already orthodox Chinese. Moreover, it must not be forgotten that, even before the Chou conquest, one of the early Ts'u rulers was an author himself, and had been tutor to the father of the Chou founder: that means to say Ts'u was possibly always as literary as China.
