孫武
One of the better-known stories about Sun Tzu, taken from Sima Qian, illustrates Sun Tzu's temperament as follows: Before hiring Sun Tzu, the King of Wu tested Sun Tzu's skills by commanding him to train a harem of 180 concubines into soldiers. Sun Tzu divided them into two companies, appointing the two concubines most favored by the king as the company commanders. When Sun Tzu first ordered the concubines to face right, they giggled. In response, Sun Tzu said that the general, in this case himself, was responsible for ensuring that soldiers understood the commands given to them. Then, he reiterated the command, and again the concubines giggled. Sun Tzu then ordered the execution of the king's two favored concubines, to the king's protests. He explained that if the general's soldiers understood their commands but did not obey, it was the fault of the officers. Sun Tzu also said that, once a general was appointed, it was his duty to carry out his mission, even if the king protested. After both concubines were killed, new officers were chosen to replace them. Afterward, both companies, now well aware of the costs of further frivolity, performed their maneuvers flawlessly.
