Cao Bin has been practicing martial arts since childhood, and her aunt is Zhang Guifei. However, Cao Bin usually keeps a low profile, and will not be arrogant and rude just because her aunt is a high-ranking imperial concubine. On the contrary, I am very humble and respectful to everyone. Before Zhao Kuangyin became emperor, Cao Bin and Chai Shizong were both generals. When Zhao Kuangyin became emperor, he asked Cao Bin, "What opinions and suggestions do you have for the officials of the dynasty?" Cao Bin said, "I am in charge of military power, which I don't know. I can't interfere." But Zhao Kuangyin insisted that Cao Bin recommended Shen Lun, thinking that he was clean and could hold an important position.
Cao Bin holds two posts, but he is never arrogant because of his high position in officialdom. He will also take the initiative to avoid other officials on the road. When those unknown small officials report things to him, he will definitely dress up and summon them again.
It is said that once, after the rebellion in the Song Dynasty. Many generals rob women and property, only Cao Bin has books and clothes in his bag. Cao Bing, who had been a soldier all his life, was modest, kind and strict with himself, which made the soldiers willing to do whatever they wanted, and the court ministers respected him very much. In 999, Cao Bin died at the age of 69 and was posthumously awarded as korean king.
Clausewitz pointed out in On War: "The bravery of soldiers is different from that of ordinary people. The bravery of soldiers must get rid of the tendency of uncontrolled and arbitrary display of strength inherent in personal courage. It must obey higher requirements: obey orders, observe discipline, and follow rules and methods. " Obviously, Cao Bin, who has this martial virtue, knows the spiritual essence of the war he participated in: whether it is cutting Shu or cutting Southern Tang, there is only one purpose, that is, defeating the other army and leading the separatist forces to the Song Dynasty; Shu people and Southern Tang people are human beings, and no matter how the regime changes, their lives and property should not be harmed. Therefore, Cao Bin's strict military discipline forbade soldiers to run amok, and the Southern Tang Dynasty was preserved.
