Yilin Verse
朝鮮之地，箕子所保，宜家宜人，業處子孫。
The land of Chaoxian; what Jizi safeguarded. Befitting family and people; their work endures through the generations.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
A lake upon a mountain, and an ancient exile finds lasting refuge. The land of Joseon (朝鮮) is where the Viscount of Ji found sanctuary. After feigning madness to survive the tyrannical court of King Zhou of Shang, Jizi was enfeoffed in the far northeast, establishing a domain that would shelter his descendants for generations. The verse celebrates this outcome: a good land for family and people, an enterprise that sustains children and grandchildren. From Influence to Revolution, the mountain's receptive openness becomes fire within a lake — the transformative upheaval that replaces an exhausted order. Jizi survived Shang's collapse and carried its culture forward under a new mandate. Revolution does not merely destroy; it preserves what is worthy by transplanting it to new soil.
