After Duke Hui's death the powerful Gao and Guo clans of Qi expelled Cui, who fled to the State of Wey.
Lu and Wey were allies of the State of Jin, a major power of the Spring and Autumn period.
Duke Qing narrowly escaped capture by exchanging clothes and position with officer Pang Choufu (逢丑父), who was taken prisoner by Jin general Han Jue mistaking him as Duke Qing.
After the battle Duke Qing was forced to plead for peace and cede territory to the state of Lu.
After the battle he reduced taxes, gave alms to orphans and the infirm, and was said to forgo alcohol and meat until his death seven years later.
