This allusion originated from Liu Chan's succession after Liu Bei's death in the late Three Kingdoms. At that time, Cao Cao's soldiers and horses were captured, and Shu defeated him naked, and then treated him very delicious and drunk, crowing every day. One day at the banquet, Wang Wei asked you how to live here. Can you miss yourself? Originally in Shu's hometown, I said it was very good here, and I was a little happy every day as if I were at home. This allusion has been handed down since then.
