Yilin Verse
六甲無子，己喪其戊。五丁不親，庚失曾孫，癸走出門。
The six jia have no sons; ji has lost its wu. The five ding are estranged; geng has lost its grandchildren; gui walks out the door.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Wind from fire orders the family through generational bonds, but here the Heavenly Stems — the cosmological markers of kinship — unravel entirely. The six jia cycle produces no sons; the ji day loses its wu partner. The five ding days refuse kinship; geng loses its grandchildren; gui flees through the gate. The verse uses the Stem-Branch system as a metaphor for family dissolution: each Stem represents a generational or relational role, and each one fails or departs. The cosmic clock that should synchronize the family's continuity breaks down completely. From The Family to Great Power, thunder above heaven surges with irresistible force. Yet power without lineage is power without legacy — the thunderous strength of Great Power means nothing if there are no heirs to carry it forward.
