Lu Zirong's uniform can be found in Confucius, who said, "Did the ancient gentleman defend himself with his sword?" Confucius said, "The ancient gentleman was loyal to quality, and was kind to keeping it. He never left the room and knew thousands of miles away. Bad is loyalty, and violence is benevolence. Why are you holding a sword? Lutz said, "Since you have heard this, please film it for teaching. 」

One day, Luz went to visit Confucius in military uniform and armed to the teeth. When he saw Confucius, he drew his sword and began to dance. He asked, "Master, an ancient gentleman used his sword to defend himself, didn't he?" ? Confucius replied: "The ancient gentleman took loyalty and righteousness as his life goal and benevolence and righteousness as his guardian. Although they don't go out of the narrow room, they know great things thousands of miles away. If there is a bad guy, use loyalty to influence him; People disturbed by riots are stabilized by benevolence and righteousness. In that case, why use a sword to use force? Lutz listened with admiration and said with emotion, "Ah! I just heard this today, and I sincerely and respectfully ask you from now on! 」
