The fifth [six], divided, reminds us of (King) Ti-yi's (rule about the) marriage of his younger sister. By such a course there is happiness and there will be great good fortune.
Ti-yi, the last sovereign but one of the Yin dynasty, reigned from B.C. 1191 to 1155; but what was the history of him and his sister here referred to we do not know. P. Regis assumes that he gave his sister in marriage to the lord of Kau, known in subsequent time as King Wan, and that she was the famous Thai-sze; - contrary to all the evidence I have been able to find on the subject. According to Khang-tze, Ti-yi was the first to enact a law that daughters of the royal house, in marrying princes of the state, should be in subjection to them, as if they were not superior to them in rank. Here line 5, while occupying the place of dignity and authority in the hexagram, is yet a weak line in the place of a strong one; and its subject, accordingly, humbly condescends to his strong and proper correlate in line 2.
