I was doing some research on Jia Chong and came across Ren Kai and Yu Chun as people he slandered out of office. Finding nothing in English sources, I searched his name and found his Chinese wikipedia. If anyone whose Chinese is really good can help me double-check my translation of the wiki, please do so since there are some areas I'm fairly certain I got wrong. Anyways, a translation of his wiki, located at
Ren Kai (223-284), zi Yuanbao, from Lean county (modern day Shandong province's Boxing county), son of Wei Minister of Ceremonies Ren Hao. Served in both the Wei and Jin dynasties. Said to be careful and hardworking with official business, and was praised by many people, however his career was hindered by Jia Chong.
Emperor Wu's Inner Circle
Ren Kai held jobs as Zhongshu assistant officer, and served the Sanqichang. In 263, Sima Zhao was made the Duke of Jin, and established the state of Jin. The Shizhong Ren Kai was made a marquis of Changguo county. He was skilled with previous works, always understanding things the first time he came across them, and was loyal and honest to the state as well as his position. He was intimate with Sima Yan, who would consult with him daily on political matters. During the Western Jin era, Zheng Chong, Wang Xiang, He Ceng, Xun Yi, and Pei Xiu were all old and wished to retire. Sima Yan was partial to them, and would not let them come before the court. He assigned Ren Kai to go to their houses to consult with them on important ideas and suggestions.
Arousing Jia Chong's hatred
Ren Kai hated how Jia Chong behaved, and couldn't bear his high rank, many times restricting Jia Chong. Although Jia Chong was very resentful, he came up with an unprecedented pla. Jia Chong praised Ren Kai, and recommended him to help the crown prince, with the intent of reducing Ren Kai's power. However, Sima Yan not only appointed Ren Kai the Crown Prince's tutor, but also had him continue to serve him, making Jia Chong unsuccessful. In 271, Qinzhou and Yongzhou were being harassed by Tufa Shujineng. Ren Kai took the opportunity to propose a prestigious officer to pacify the borderlands, and recommended Jia Chong. The zhongshuling Yu Chun also supported this, and Sima Yan ordered Jia Chong to take over the military affairs of Chang An. Xun Xu came up with a plan to let Jia Chong remain in Luoyang.
At that time, the court divided into two factions under Ren Kai and Jia Chong. Sima Yan attempted to reconcile them, but the two men held a deep hatred, on the surface showing respect, but holding extreme resentments in their hearts. Someone proposed a plan to Jia Chong, to first have Ren Kai leave the Emperor's side; Jia Chong would then praise Ren Kai's ability, and recommend him to select choice works of scholarship. Sima Yan appointed Ren Kai Libu Shangshu (Minister of History), as well as offering him a General rank. Ren Kai was impartial with the works he selected, and did his work diligently, but had few opportunities to meet with the Emperor. Jia Chong at this time had Xun Yi and Feng Dan slander Ren Kai's extravagance, such as using the Imperial utensils, in addition to sending his Shangshuyoupushe (Left Supervisor of the Masters of Writing), and had the King of Gaowang Sima Gui present a memorial to Sima Yan. Sima Yan dismissed Ren Kai from office. A later investigation would discover that imperial utensils were really bestowed on Ren Kai's wife and kids by the Princess Qichang? (Cao Rui's daughter). However, since Ren Kai had been dismissed from office and slandered, grew apart from Sima Yan. Later after capturing Shan Tao, he's be appointed Henan magistrated, once again dismissed from office, and would later get appointed Supervisor of Attendants.
Ren Kai from these experiences continued to be hardworking and scrupulously abided by his duty, but Jia Chong and his clique said he and Li Jinling conspired with Liu You(?), shangshu Du You as well as the Commandant of Justice Liu Liang made an appeal for Ren Kai, but they were all dismissed from office. Having lost office again, he turned to drinking, spending 10,000 dollars on a meal. At this time, Ren Kai recieved Sima Yan's summons, and was greeted by Sima Yan, which made Ren Kai weep. He'd later be appointed as a Grand Servant, as well as a Minister of Ceremonies.
Losing the will to live
In 283, the Shangshuzuopushe (Right Supervisor of the Masters of writing, and Youguangludaifu (Right Glorious Grand Master), Wei Shu was appointed Situ, replacing Shan Tao. Ren Kai was ordered to instruct him. Wei Shu had formerly been recommended for a promotion by Ren Kai, and was now one of the Three Ministers (I think), while Ren Kai was only a minister, never achieving the rank of the Three Ministers, with everyone feeling he was not worthy. Ren Kai lost his ambition, grew depressed and died, having lived to 61, with the posthumous title of Yuan.
