People who know historical records should mostly know the story of Sun Wu beheading maids. This story is about Sun Wu practicing formation with ladies-in-waiting. At that time, the two concubines of the king of Wu disobeyed orders. Sun Wu killed them all in a rage, thus establishing his prestige in the army.

During the Spring and Autumn Period, Sun Tzu and I took Sun Tzu's Art of War to visit the King of Wu, and then we wanted to see the real effect of Sun Tzu's Art of War, so we ordered Sun Wu to train ladies-in-waiting and show his ability to lead troops.

But the maids themselves are spoiled. Even if they wear men's clothes and hold halberds in their hands, they are free and loose. At that time, I was sent to introduce my password to these people, and they needed to do whatever they said. When he really said the password, the ladies-in-waiting didn't take it seriously, but when Sun Wu beat the drums to give orders, the ladies-in-waiting were wobbly. Sun Wu emphasized twice that it didn't work, so he let the two leading captains come out of the queue, which happened to be the princess of the prince. But Sun Wu not only wanted to establish his prestige in the army, but also wanted to train a disciplined army to show his talents to the prince, so he killed two concubines without hesitation.

Later, because Sun Wu killed the emperor's two concubines, the emperor stopped pursuing them, causing the ladies-in-waiting to be frightened. They listened to Sun Wu's orders and began to do actions. Everyone's attitude changed and they were very strict. Later, the prince of Wu found that Sun Wu was really good at fighting, so he was named general.
