Yilin Verse
公孫駕驪，載聘東齊。延陵說產，遺季紵衣。
Lord Gongsun drives black horses, bearing betrothal gifts east to Qi. Yanling speaks of his estate and leaves Jizi a ramie robe.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
A lord harnesses dark horses to carry betrothal gifts east to Qi, while Yanling's Ji Zha, visiting Zheng, admires Zichan's character and presents him with a fine ramie robe. According to the Zuo Zhuan, Ji Zha of Wu toured the states evaluating their governance and music; in Zheng, he and Zichan exchanged gifts as tokens of mutual respect between worthy statesmen. From Creative to Increase, wind and thunder reinforce each other — seeing virtue, one follows; recognizing faults, one corrects. The verse embodies Yi's spirit: diplomatic exchange that enriches both parties. The betrothal gifts and the gifted robe are not transactions but investments in relationship, each act of generosity amplifying the other's capacity.
