Interpretation: Pei Songzhi's Notes on the Three Kingdoms. Biography of the Three Kingdoms, Wu Zhi and Wu Zhu: "In the first month of the eighteenth year, Cao Gong attacked your weakness, but his strength refused for more than a month. Cao Gong looked at the right army and sighed at its Su Qi, so he retired. " Pei's note: Yue ... right to travel five or six miles, and then advocate. When everyone saw that Zhou Zhen was purged by the soldiers, they sighed,' My son should be like this, and Liu Jingsheng's son should be like a dolphin and a dog's ear.' "

Commentary: Cao Cao and Sun Quan were at loggerheads, but Cao Can failed to break them up. Seeing that Wu Jun's lineup was purged, Sun Quan's bravery was unusual, which made him deeply envious. So he issued a compliment of "having a child like Sun Zhongmou", which is another word of scolding the department. Later generations often use this metaphor to hope that the younger generation will have wisdom. Song Xin Qi Ji's "Nanxiangzi Deng Jing Kou Gu Bei Ting Huai": "I was young and didn't stop the Southeast War. Who is the world hero? Cao Liu. Children should be like Sun Zhongmou. "
