In fact, as far as Ji Kang is concerned, his character is rather arrogant, not attached to powerful forces, and he has the pride of a scholar. But I think as a literati, his integrity should make him more inclined to the orthodox royal family, that is, Cao Zhi at that time. He didn't like Sima, and he always wanted to seek power and usurp the throne with an absolute monarch. In fact, Ji Kang didn't show too obvious bias in his early days, but later he married Changle Zhu Ting, the daughter of Wang Pei Cao Lin, and of course he was more biased towards his family. Later, Dan Tao asked him to be an official, coupled with some bad behaviors of Sima Group, Ji Kang was disgusted with these and of course opposed Sima.
In essence, Ji Kang is still a lofty and indifferent person. Personally, I don't want to associate such a beautiful person with a sinister political struggle. Moreover, Ji Kang is not like those so-called literati and celebrities who pretend to be lofty and write pens for the ruling group.
