Wu Zixu
In the kingdom of Wu, Wu Zixu became a trusted advisor of Prince Guang and helped him assassinate his cousin King Liao of Wu. Prince Guang ascended the throne and was known as King Helü of Wu. In 506 BCE, Wu Zixu persuaded King Helü to invade Chu. The Wu army routed the Chu army commanded by Nang Wa in the historic Battle of Boju and captured and destroyed the Chu capital Ying. Both Nang Wa and King Zhao of Chu fled, and Shen Yin Shu died in battle. Chu, one of the most powerful states in the Spring and Autumn period, would never regain its former strength. Fei Wuji's persecution of Prince Jian and Wu She directly contributed to the decline of Chu and he is remembered as one of the top villains in Chinese history.
