Wei Guan
Zhong Hui had long harboured the intention of rebelling against Wei. When he saw that Deng Ai behaved in an autocratic manner even though his military command was authorised by the Wei imperial court, he secretly reported to the court that Deng was plotting a rebellion. He was skilled in imitating people's handwriting. After intercepting a report written by Deng Ai to the Wei imperial court, he edited the report to make it sound arrogant and demanding. At the same time, he also destroyed a letter from Sima Zhao to Deng Ai. The Wei government fell for Zhong Hui's ruse and ordered Deng Ai to be arrested and transported back to Luoyang in a prison cart. Sima Zhao was worried that Deng Ai would not submit, so he ordered Zhong Hui and Wei Guan to arrest Deng Ai. With Zhong Hui and his troops following behind, Wei Guan went to Deng Ai's camp in Chengdu and used Sima Zhao's letter of authorisation to order Deng's soldiers to put down their weapons. Deng Ai was arrested and placed in a prison cart.
