郑国大夫不失时机吟诵《诗经.郑风.将仲子》中“仲可怀也，人之多言，亦可畏也”。意在表达，如果晋国不放卫侯，将会引起众怒，不但影响晋国国威也牵连晋侯形象，人言可畏啊。至此，经过多轮“吟诗”，晋侯终于点头，答应放人。

The senior officials from the Kingdom of Zheng seized the opportunity to recite the line "You, O Zhong, are to be loved, But the talk of people, Is also to be feared." from Jiang Zhong Zi in the Odes of Zheng in the Book of Songs. This was to express that if the Kingdom of Jin did not release the Duke of Wei, it would inspire the wrath of the people, not only affecting the national prestige of Jin, but also affecting the image of the Marquis of Jin himself, and that gossip is a thing to be feared. At that point, after several rounds of poetry recitation, the Marquis of Jin finally gave the nod and agreed to release him.
