Fan Li
Taking advantage of Fuchai's expedition to his north to defeat Qi, Goujian led his army and successfully attacked the Wu capital, killing the Wu crown prince, You. In the 24th year of his reign (473 BC), Goujian led another expedition against Wu, laying siege to the capital for three years before it fell. When a surrender from Fuchai was refused, Fuchai committed suicide and Wu was annexed by Yue. After his victory, Goujian ruthlessly killed Fuchai's scholars, even those who helped him (including Bo Pi), not allowing himself to make the same mistake Fuchai had made by sparing the lives of his enemies. However, Goujian would not stop there; he would later force Wen Zhong to commit suicide; Fan Li, knowing that Goujian was a man who can share woe but not wealth together, left Goujian after the defeat of Wu.
