Last king of Wu who spared Goujian and lived to regret it.
Compare King Fuchai of Wu with another historical figure:
King Fuchai of Wu defeated the state of Yue at the Battle of Fujiao. He captured King Goujian of Yue and took him as a hostage, but later released him after Goujian feigned submission, a decision that proved fatal.
Fuchai, persuaded by his minister Bo Pi and deceived by Goujian's apparent loyalty, released the Yue king. This act of clemency allowed Goujian to return to Yue and secretly rebuild his strength for revenge.
Fuchai convened a meeting of feudal lords at Huangchi and was recognized as hegemon. However, while he was away, Yue attacked Wu's capital, weakening Wu and exposing the vulnerability of his overextension.
Yue forces under Goujian conquered Wu. Fuchai, surrounded and defeated, committed suicide. His death ended the Wu state, and his earlier decision to spare Goujian was seen as the cause of his downfall.
