This book mainly describes the legendary life of Wu Zixu, a famous statesman and military strategist in the Wu Kingdom at the end of the Spring and Autumn Period. From his extraordinary talents and great ambitions to his father and brother being killed and being forced to flee, he was later reused by King Helu of Wu. He defeated Chu in five battles with the help of Wu's soldiers and finally avenged the death of his father and brother; and then assisted King Helu of Wu to dominate the princes. Later, during the struggle for hegemony between Wu and Yue, he was jealous of Wu King Fu Chai and died unjustly in his later years. His body was thrown into the Qiantang River. Later generations of people felt his loyalty and built temples to worship the tide god, which lasted for more than 2,500 years. Famous idioms and allusions such as "Wu Zixu passed Zhaoguan and died overnight", "muddled through the pass", "three orders and five orders", "digging graves and whipping corpses", "lying on firewood and tasting courage", "the mantis stalks the cicada, the oriole behind", etc. Are all related to Wu Zixu's life experience.
