Chen Gong
Chen Gong told Lü Bu, "Cao Cao has come a long way and he won't be able to last long. General, you can bring some troops with you and set up a camp outside the city, while the others and I will remain behind to defend the city. If the enemy attacks you, I'll lead the city's soldiers to attack them from behind. If they attack the city, you can reinforce the city from outside. Within ten days, the enemy's supplies will be depleted and we can defeat them easily." Lü Bu agreed with Chen Gong's idea. However, Lü Bu's wife said, "In the past, the Caos treated Gongtai (Chen Gong) like a newborn child, but he still turned against them and joined you. Now, the way you treat Gongtai is no lesser than how Cao Cao treated him, and you intend to entrust the entire city to him, along with your family, while you venture out alone? If something happens, I won't be your wife anymore!" Lü Bu then changed his mind.
