Changing lines (counted from the bottom): 2, 4, 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 27 頤, line 1
舍爾靈龜，觀我朵頤，凶。
The first line, undivided, (seems to be thus addressed), 'You leave your efficacious tortoise, and look at me till your lower jaw hangs down.' There will be evil.
Hexagram 27 頤, line 3
拂頤，貞凶，十年勿用，无攸利。
The third line, divided, shows one acting contrary to the method of nourishing. However firm he may be, there will be evil. For ten years let him not take any action, (for) it will not be in any way advantageous.
The two hexagrams
Hexagram 58 兌 — judgment
亨。利貞。
Tui intimates that (under its conditions) there will be progress and attainment. (But) it will be advantageous to be firm and correct.
Hexagram 27 頤 — judgment
貞吉。觀頤，自求口實。
Î indicates that with firm correctness there will be good fortune (in what is denoted by it). We must look at what we are seeking to nourish, and by the exercise of our thoughts seek for the proper aliment.
The changing lines of hexagram 58
| Line | Chinese | Legge |
|---|---|---|

| 4 | 商兌，未寧，介疾有喜。 | The fourth line, undivided, shows its subject deliberating about what to seek his pleasure in, and not at rest. He borders on what would be injurious, but there will be cause for joy. |
| 5 | 孚于剝，有厲。 | The fifth line, undivided, shows its subject trusting in one who would injure him. The situation is perilous. |
