Wu Zixu
Ten years after Goujian was allowed to return to Yue, while King Fuchai waged another campaign in the state of Qi, King Goujian made a backstabbing attack on Wu. Due to years of neglect, Wu fell easily, just as Wu Zixu had warned. Bo Pi was executed by King Goujian for disloyalty to the former King Fuchai and, ironically, for accepting gifts from foreign rulers.
