Wu Zixu
Wu Zixu was the second son of Wu She, the Grand Tutor of the crown prince Jian of the state of Chu. In 522 BC, Fei Wuji, a corrupt official was sent to Qin to select a bride for the prince. King Ping of Chu received a princess from the state of Qin as a bride for his son, but decided to keep her for himself upon seeing her beauty. Fei Wuji, having gained favour from the King, convinced King Ping that Wu She and the crown prince himself would start a rebellion due to the bride being from Qin, and persuaded the king to execute Wu She. Before his death, Wu She was forced, under duress, to send a letter to his sons, Wu Shang () and Wu Zixu, which asked them to join him in the capital. While both realized that this was a trap, Wu Shang decided to go to the capital to die with his father. Wu Zixu, promising revenge, fled to the state of Wu.
