Lü Meng was a renowned officer under Sun Quan during the Three Kingdoms period of China. He served as the commanding general in the invasion of Jing Province that led to the death of Guan Yu.

It was said that Lü Meng focused entirely on martial skills until he was admonished by Sun Quan. Lü Meng used to say that military matters take away his time and he had no time to read, but Sun Quan stated that he himself had to tend to matters both big and small in his land, even so, he had the time to read and enhance himself. Lü Meng was enlightened, and started to take up scholarly pursuits with another general Jiang Qin. Soon his breadth of knowledge became so broad that even some elder Confucians could not match him, and Sun Quan was so impressed at Lü's improvements that he often used Lü Meng as a role model for his other officers.
