Original: Lu Su wanted to find Yang and consulted with Meng. He was surprised and said, "You are a talented person, not a monk!" " Lv Meng said: "The upright people have been watching for a few days. You know how late it is when you look at something so late." Lu Su met Lu Meng's mother and became friends with Lu Meng.

When Lu Mengchu didn't learn Chinese, Sun Quan enlightened him and another brave general, Jiang Qin, saying, "Now you are all in important positions and in charge of state affairs. You should read more and make continuous progress." Monroe said: "I often suffered many things in the military camp, so I am afraid that I can't study any more." Sun Quan patiently pointed out: "Do I want you to learn classics to be a doctor?

Please read more books, learn about the past and increase your knowledge. Who do you think can have as much business as me? When I was young, I read The Book of Songs, Shangshu, Book of Rites, Zuo Zhuan and Guoyu, but I never read Zhouyi. Since I took office, I have carefully studied Three Histories, Historical Records, Han Shu, Eastern View of the Han Dynasty and the laws of sending troops.

I think I have many benefits. Like you two, you are smart and temperament, and you will certainly benefit from your study. How can you not study? You should read Sun Tzu, Tamia Liu, Zuo Zhuan, Mandarin and Three History first. Grandson once said,' It's no good dreaming without eating all day and sleeping all night. It is better to study. "

Emperor Guangwu of the Eastern Han Dynasty shouldered the heavy responsibility of directing the war, but he still couldn't let go. Cao Cao also said that he was old and eager to learn.

After Zhou Yu took charge of Wu County, Lu Su passed by Monroe's residence on his way to the office, and Monroe entertained him with wine. Lu Su still looks at people from an old perspective, thinking that Monroe is brave and foolhardy, but when they talk about what's going on in the world at the banquet, Monroe has many insights, which shocked Lu Su. After the banquet, Lu Su sighed, "I always thought that my younger brother only had martial arts. Today, my brother is outstanding in knowledge, and it is really not Wu Xia Amon. "

Lv Meng said, "I have been away for three days, but I am more impressed. Dude, it's really difficult to be a commander in chief today, but he is not as talented as Zhou Gongjin (Zhou Yu), second only to Guan Yu.

Guan Yu is an old man who studies tirelessly. He reads Zuo Zhuan fluently. Honesty and frankness is a hero's character, but he is quite conceited. Since we are adjacent to him, we should have a good solution. "He planned three schemes for Lu Su, and Lu Su accepted them.
