Quan Cong
Sun Quan did not heed Quan Cong's advice and proceeded with sending forces to invade Zhuya and Yizhou. After 80 to 90 percent of his troops died from illness and disease within the first year of the campaign, Sun Quan started to deeply regret his decision. When he spoke to Quan Cong again, the latter told him: "I think that those who didn't attempt to dissuade Your Majesty from launching this campaign aren't loyal towards Your Majesty."
