Once upon a time, there was a young and impetuous scholar named Li Wencai. One day, he got into an argument and, acting on impulse, drew his sword. Fortunately, others intervened in time, preventing a bloody incident. Afterwards, Li Wencai deeply regretted his rash actions, realizing his impulsiveness. He then changed for the better, studied hard, and eventually became a virtuous and capable official, warning others to be cautious and avoid acting out of anger.
