Xiahou Xuan
When Xiahou Xuan was 20 years old, he was appointed as a Gentleman of Scattered Cavalry () and Gentleman of the Yellow Gate () under the Wei government. One day, in the front of the emperor Cao Rui, he expressed his abhor about sitting together with Mao Zeng (), the brother of Cao Rui's empress, Empress Mao. This incident aroused the anger of the emperor, who demoted Xiahou Xuan to a supervisor of the Feathered Forest Imperial Guard ().
