Zhao Yao knew the emperor's rewards were not given with good intentions because the emperor gifted him several new books authored by the emperor himself and required him to memorize them all. If he couldn't, he would be punished with copying them.
Because of this, Zhao Yao hated the emperor, his annoying father, even more. If possible, he genuinely wished he could have a different father.
The emperor loved teasing his youngest son, and every time he saw his little son's angry face, he found it amusing.
Sun Kui felt that the emperor was always bullying the tenth prince, and the more he bullied him, the more the tenth prince would hate his father. He kindly reminded the emperor not to bully the tenth prince too much, but the emperor didn't care at all. He even said that it's best to bully him while he's young because once he grows up, it wouldn't be as fun.
In the emperor's words, sons are only fun and easy to bully when they're young; once grown, they're no longer fun.
