Sun Wu was a native of the State of Qi, who came to the State of Wu to escape the chaos of war. When he was recommended by Wu Zixu to Lu Lu, Sun Wu once dedicated thirteen articles of the Art of War that he had written, which was valued by Lu Lu. In order to verify Sun Wu's art of war, Lu Lu asked Sun Wu to train the beauties in the palace. In order to solemnize military discipline, Sun Wu beheaded two of king Wu's favorite concubines who served as captains, and the palace women retreated to obey orders. Only then did he realize Sun Wu's talent and let him rule the army.
