Yilin Verse
俱為天民，雲過吾西，伯氏嫉妬，與我無恩。
All alike are heaven's people; clouds pass west of me. The elder brother harbors jealousy; he shows me no kindness.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Heaven above the mountain shifts into mountain over water — Youthful Folly's bewildered darkness. All are subjects under heaven, yet clouds drift past to the west without pausing. The elder brother harbors jealousy and shows no kindness. The verse depicts familial estrangement: though bound by common origin, one sibling turns hostile while the other can only watch opportunity pass like drifting clouds. The 'elder brother's jealousy' resonates with numerous Spring and Autumn succession crises where brothers contended for inheritance. From Retreat to Youthful Folly, the mountain's strategic withdrawal encounters the spring that cannot yet find its way. The retreating figure withdraws not from enemies but from kin — the most painful form of retreat, where the folly lies not in ignorance but in the refusal of one's own blood to offer grace.
