Yilin Verse
牛驥同堂，郭氏以亡；國破為虛，主君奔逃。
Ox and thoroughbred in the same hall -- the Guo clan perishes thereby. The state falls to ruin; the lord flees in exile.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Thunder breaks from the earth, but the thoroughbred and the ox share the same stall — an idiom for mixing the superior with the inferior until both are degraded. The Guo clan is destroyed; the state collapses into ruin, and its lord flees. 'Niu ji tong tang' is a classical warning against failing to distinguish quality: when a thousand-li horse is stabled with draft oxen, its gifts are wasted and the institution that tolerated this confusion pays the ultimate price. From Enthusiasm to Coming to Meet, the resonance is cautionary. Wind moves beneath heaven, the ruler issuing commands to all quarters. But Coming to Meet also warns of the yin force that enters unbidden — the inferior element that infiltrates through indiscriminate welcome. The Guo state fell because it could not tell its horses from its cattle.
