What is Han Fei’s attitude towards the abdication system in ancient times?

Both Zhuang Zhou's statement and Han Fei's explanation are full of joking elements, and it is enough to just take them as a joke.

However, the same Han Fei not only did not admit that there was a system of abdication in ancient times, but also said that Shun and Yu could inherit the throne because of "regicide by ministers". He believed in "Han Feizi·Shuo Sui": "Shun forced Yao, Yu forced Shun, Tang defeated Jie, and King Wu defeated Zhou. These four kings were the ones whose ministers killed their kings!" Han Fei did not describe these people seizing power. It did not mention the details of whether all four kings were beheaded, but it was clearly stated that the successors used tough methods of "forcing", "releasing" and "cutting". Obviously, this is completely different from the abdication system. Two things.
