Sun Hao
After ascending the throne, Sun Hao appointed Wan Yu as a Central Regular Mounted Attendant (散騎中常侍), along with Wang Fan, Lou Xuan and Guo Chuo (郭逴). Later into his reign, Sun Hao turned out to be a cruel, extravagant and inept emperor, so Puyang Xing and Zhang Bu started regretting their decision to put him on the throne. When Wan Yu heard about their complaints, he secretly reported them to Sun Hao, who had them executed along with their families. Among his colleagues, Wan Yu got along well the most with Lou Xuan and the least with Wang Fan. He particularly detested Wang Fan as he believed that Wang Fan leveraged on his close relationship with Sun Hao to gain the emperor's favour. Wan Yu and another official, Chen Sheng (陳聲), often slandered Wang Fan in front of Sun Hao. Over time, Sun Hao also gradually hated Wang Fan more and more because the latter often spoke up against his outrageous behaviour. Sun Hao finally found an excuse to execute Wang Fan in 266.
