Lu's refusal to send his wife, in 487 BC Duke Dao dispatched Bao Mu to invade Lu with the Qi army, taking the cities of Huan (讙) and Chan (闡). Lu was forced to send Ji Ji to Qi, and Qi returned the two cities to Lu. In the same year Duke Dao killed Bao Mu for trying to incite rebellion among the Qi princes. Death In 485 BC, the fourth year of Duke Dao's reign, the states of Wu, Lu, Zhu and Tan (郯) invaded Qi. Fuchai, the king of Wu, was the commander of the allied forces as Wu was at the time the most powerful state of China. By the time the invading forces reached southern Qi, Duke Dao had been killed by a Qi official, probably Tian Heng, who had succeeded his father Tian Qi as leader of the Tian clan. When the obituary reached King Fuchai, he suspended the campaign and for three days cried outside the army camp, according to the etiquette of the time. After the mourning period was over, Fuchai launched a naval attack on Qi, but was defeated and forced to retreat. Duke Dao's son Prince Ren subsequently ascended the throne, to be known as Duke Jian of Qi.
