 2. In Records of the Three Kingdoms, Pei Songzhi quoted Jiang Biao Zhuan: "Guangwudang military and political affairs; don't let go." During the Three Kingdoms period, Lv Meng was a general of the State of Wu. Once, he ordered 30000 soldiers to attack Jingzhou with more than 80 ships. The sailors were all dressed in white, and a large number of elite soldiers were ambushing in the cabin. At night, when the boat reached the Dangyang River, the Han soldiers in the beacon tower shouted abuse at him. Wu Jun pretended to be a merchant ship and asked to dock for shelter. Han soldiers believed it. At about two o'clock, the Wu army on board suddenly attacked and occupied the beacon tower. Later, Monroe led the troops to enter Jingzhou lightly. Lv Meng fought bravely, but he refused to learn at ordinary times. Sun Quan advised, "You should read some history and the art of war, so that you can fight more skillfully." Sun Quan said, "Emperor Wu of the Han Dynasty was a soldier, but he couldn't let go." Since then, Lv Meng has been studying hard and has benefited a lot.
