Lü Meng
Later that year, during the invasion of Jing Province, after Lü Meng received the surrender of Mi Fang, the Administrator of Nan Commandery (南郡; around present-day Jiangling County, Hubei), he did not immediately order his forces to occupy the city and instead held celebrations on the beach. Yu Fan reminded Lü Meng, "As of now, only General Mi has surrendered to us. We cannot trust that everyone in the city is willing to surrender too. Why are you celebrating here instead of quickly taking control of the city?" Lü Meng followed Yu Fan's advice. There was actually a planned ambush in the city but it was not successfully carried out because Lü Meng heeded Yu Fan's warning in time.
