Historically, Zhao Dun (Deng) was a psychopath. Historically, Zhao Dun was a dutiful son, and he was very sensible when he was in the East Palace. From his accession to the throne to his illness (Shao Xi's second year), he was a well-behaved monarch. In the history books, there is an evaluation that "Shao Xi was in the early government, so it is desirable to take it", and people's taxes have been reduced and exempted for many times, and official management has been rectified. But he was paranoid, especially four years later, Shao Xi became the most unfilial emperor in history by drinking like a dog, loving actresses and trusting eunuchs. After his illness, he was called "Mad Emperor" and was deposed by imperial clan and prime minister Zhao Ruyu.
