Why was Cao Pi ridiculed by Sun Quan when he appointed Jia Yi as Qiu?

There are two reasons why Cao Pi's appointment of Jia Xu as Qiu was ridiculed by Sun Quan. One is that Sun Quan thinks Jia Xude is unworthy, and the other is that Sun Quan thinks that Cao Pi doesn't know how to avoid suspicion. After Cao Pi proclaimed himself emperor, he immediately appointed Jia Xu, the hero, as Qiu. Sun Quan thought that the character of this minister needed to be considered, and he was eagerly raised as the son of Jun, so he was only? Laugh? . (1),? Poison man? Jia Xu's misconduct was Jia Xuyi, an adviser during the Three Kingdoms period. Poison man? Famous, although few people think that his conduct is improper, Sun Quan is very suspicious of his conduct. At that time, the great reason for the collapse of the Eastern Han Dynasty was Jia Xu's chaotic politics, which led to the turmoil in the imperial court. Jia Xu also went his own way to send troops to attack Chang 'an, which accelerated the collapse of the Eastern Han Dynasty. Therefore, Sun Quan thought that Jia Xu was uneasy and kind. Moreover, Jia Xu changed hands many times at that time, and he didn't know whether he was sincere or not, so Sun Quan Jia Xu always held a contemptuous attitude. In addition, some of Jia Xu's schemes are more sinister, which is also an important reason why Jia Xu's character was scorned by just Sun Quan. (2) Cao Pi eagerly rewarded the hero Cao Pi. In fact, the road to the throne was not very smooth. In the end, he was able to inherit Cao Cao's unification, and Jia Xu was the biggest hero. Among Cao Cao's three favorite heirs, Cao Chong withdrew from the competition because of his early death, leaving only Xelloss and Cao Zhi's brothers fighting with each other. Cao Cao himself was vacillating between Cao Pi and Cao Zhi, so he quietly asked Jia Xu's opinion. Jia Xu knew Cao Cao's confusion, so he used the actual examples of Yuan Shao and Liu Biao to imply that Cao Cao chose Cao Pi, so Cao Cao made up his mind to let Cao Pi inherit the unification. After xelloss ascended the throne smoothly, he immediately named Jia Xu as Qiu, and he didn't know how to avoid suspicion at all, which also led to the fact that xelloss ascended the throne was always discussed by the people. Although the awarding of Jia Xu after Cao Pi proclaimed himself emperor has nothing to do with Sun Quan, how can Cao Pi and Jia Xu, the monarch and the minister, not understand the importance of avoiding suspicion, and their conduct is criticized by others, not be ridiculed?
