Hexagram 31 咸 changing to hexagram 64 未濟
Changing lines (counted from the bottom): 2, 3, 5, 6.
What to read
Four changing lines: read the two unchanged lines of the resulting hexagram; the lower one is the main one. (Rule set out by Zhu Xi in the Yixue qimeng.)
Hexagram 64 未濟, line 1
濡其尾，吝。
The first line, divided, shows its subject (like a fox) whose tail gets immersed. There will be occasion for regret.
Hexagram 64 未濟, line 4
貞吉，悔亡，震用伐鬼方，三年有賞于大國。
The fourth line, undivided, shows its subject by firm correctness obtaining good fortune, so that all occasion for repentance disappears. Let him stir himself up, as if he were invading the Demon region, where for three years rewards will come to him (and his troops) from the great kingdom.
The two hexagrams
Hexagram 31 咸 — judgment
亨。利貞。取女吉。
Hsien indicates that, (on the fulfilment of the conditions implied in it), there will be free course and success. Its advantageousness will depend on the being firm and correct, (as) in marrying a young lady. There will be good fortune.
Hexagram 64 未濟 — judgment
亨。小狐汔濟，濡其尾，无攸利。
Wei Zî intimates progress and success (in the circumstances which it implies). (We see) a young fox that has nearly crossed (the stream), when its tail gets immersed. There will be no advantage in any way.
