曹髦
The Wei emperor Cao Mao ( 254–260) was particularly fond of the literati, so he became close to notable members of the literati such as Sima Wang, Pei Xiu, Wang Chen and Zhong Hui. Cao Mao was known for being impatient and he wanted them to come for the banquets he hosted in the shortest time possible. Since Pei Xiu, Wang Chen, Zhong Hui and the others served as officials in the imperial palace, they were able to make it on time. Sima Wang, however, took more time to reach the imperial palace because he was stationed in a military camp. Cao Mao then gave him a fast-moving chariot so that he could travel faster, and also provided him five imperial guards as escorts.
