Wu Zixu
During the Spring and Autumn period in ancient China, the four great clans in the Qi state compete among themselves to win a dominant position in politics. Despite the animosity between their respective fathers, Sun Wu and Guo Wujiu develop a close friendship, and they are tutored in military strategy by the renowned militarist Tian Rangju. Meanwhile, in the Chu state, Wu Zixu becomes a fugitive after his father is wrongly accused of treason and his entire family is exterminated by the incompetent King Ping of Chu. Wu Zixu settles in the Wu state with help from Sun Wu and Wujiu.
