In 230, Cao Rui promoted Man Chong to General Who Attacks the East (). In the winter of that year, after receiving intelligence that the Wu emperor Sun Quan was planning to attack Hefei, Man Chong immediately requested for reinforcements from Yan and Yu provinces and stepped up the defences at Hefei. When Sun Quan heard about it, he called off the attack on Hefei. Man Chong knew that Sun Quan was only pretending to retreat to put him off guard, and would come back to attack Hefei again once the reinforcements left. He was proven right as Sun Quan attacked Hefei after about 10 days. However, as Hefei was well-defended, Sun Quan's forces could not breach the walls and had to withdraw.
