On one occasion, he ordered thirty thousand soldiers to attack Jingzhou with more than eighty ships. The sailors were all dressed in white, and a large number of elite soldiers ambushed in the cabin. At night, when the boat reached the Dangyang River, the Han soldiers on the beacon tower sternly questioned him. Wu Jun pretended to be a merchant ship and asked for shelter, but Han soldiers believed him. About the second watch, Wu Jun suddenly attacked the ship and occupied the beacon tower. Subsequently, Monroe led the troops into Jingzhou and took Jingzhou lightly.
Lv Meng fought bravely, but refused to study at ordinary times. Sun Quan advised, "You should read some history and art of war, so that you can use your troops better." Sun Quan said, "The former Emperor Wu of the Han Dynasty was born in the army, but he never put down his book." Since then, Lv Meng has been diligent in self-study and has benefited a lot.
Never put down a book: never leave a book in your hand. This book describes the diligence of reading.
