Origin and Story of 庆父不死，鲁难未已

In 662 BC, after Duke Zhuang of Lu passed away, his half-brother Qing Fu, consumed by greed and ambition, plotted to usurp power. He swiftly orchestrated the assassination of the newly enthroned Gongzi Ban, and later, even Duke Min, whom he had initially installed as ruler. These actions plunged the state of Lu into severe chaos, leading to two rulers being killed within two years, and earning him the profound hatred of the populace.

Observing this escalating crisis, Zhongsun Qiu, a minister from the state of Qi, famously remarked, "Unless Qing Fu is eliminated, the troubles of Lu will never cease." Indeed, Qing Fu eventually fled to the state of Ju, but knowing his egregious crimes and facing certain punishment upon return, he committed suicide en route.

This idiom is now used to emphasize that a crisis or problem will persist unless its main instigator or root cause is dealt with.
