Dong Yun
In 244, Dong Yun succeeded Fei Yi as Prefect of the Masters of Writing () and attempted to follow Fei Yi's daily schedule and lifestyle when he held that appointment. However, within ten days, Dong Yun quickly realised that his work was gradually piling up. He sighed: "The ability of a talented person can be so significantly different from that of another. I think I can never catch up (with Fei Yi). Despite working all day long, I still have many things that I haven't attended to yet."
