公孫淵
When Yu Fan was living in exile, he was still very concerned about state affairs. For example, he strongly opposed Sun Quan's idea of sending an army across the sea to attack the warlord Gongsun Yuan in Liaodong (in northeastern China). However, he did not dare to voice his opinion directly to Sun Quan, so he asked Lü Dai to help him pass his message to Sun Quan, but Lü Dai did not do so. Sun Quan heard about it later and was so angry with Yu Fan for opposing his decision that he banished Yu Fan further south to Mengling County (猛陵縣), Cangwu Commandery (蒼梧郡), which is located in present-day Guangxi. Sun Quan sent a fleet to attack Gongsun Yuan, but he regretted his decision later when storms caused the fleet to sustain heavy damage and losses. He remembered Yu Fan and quickly sent messengers to Jiao Province to fetch Yu Fan back to Jianye, but Yu Fan was already dead by then.
