The changing lines of hexagram 16
| Line | Chinese | Legge |
|---|---|---|
| 1 | 鳴豫，凶。 | The first line, divided, shows its subject proclaiming his pleasure and satisfaction. There will be evil. |
| 3 | 盱豫，悔。遲有悔。 | The third line, divided, shows one looking up (for favours), while he indulges the feeling of pleasure and satisfaction. If he would understand!—If he be late in doing so, there will indeed be occasion for repentance. |
| 5 | 貞疾，恆不死。 | The fifth line, divided, shows one with a chronic complaint, but who lives on without dying. |
