여몽
Lü Meng was unhappy with Gan Ning, a general under Sun Quan, because of his violent and murderous ways. There was one incident where Lü Meng was so furious with Gan Ning that he wanted to kill him. Gan Ning also infuriated Sun Quan on a number of occasions when he defied his lord's orders. When Lü Meng heard about it, he told Sun Quan: "The Empire has yet to be pacified. Fierce generals like Gan Ning are hard to come by. You should tolerate him." Sun Quan heeded Lü Meng's advice and treated Gan Ning generously. In return, Gan Ning served Sun Quan faithfully until his death.
