Allusions (1) According to anecdotal reports, after the death of Qin Shihuang, Hu Hai who passed the throne to his son was called Qin Ershi. Zhao Gao, a big traitor, pointed out that he was young and ignorant, and it was best to avoid seeing ministers, so as not to expose himself. Zhao Gao, acting as an agent, was happy to hide in the harem, indulge in debauchery and enjoy himself. In just three years, Qin Shihuang's hard-earned land was destroyed, so later generations accused him of going easy on him and losing everything. We called him the second sai-jo just like Qin Ershi.
(2) or refers to Liu Bei's son Liu Chan. Deceived his old man's house, and the Shu State, which was created with great efforts, was completely defeated. A classic sentence: if you are happy here, don't think about it!
