Lu Meng declined on the grounds that there were many affairs in the military camp. Sun Quan said: "Do I want you to study classics and history and become a knowledgeable scholar? It's just that you should learn widely and not master it deeply. You said you have to deal with many things, which one can compare with what I can handle. What about business? I often read, and I felt that I had gained a lot." Lu Meng began to study.
