Who is the protagonist of the idiom "Happy to miss Shu"?

The protagonist of "Happy to Think of Shu" is Liu Chan, the later leader of the Shu Han Dynasty during the Three Kingdoms period.

People often refer to people who are so happy that they forget to return, or who are so happy that they forget their origins and have no thoughts about their homeland. This is called "being happy but not thinking about Shu". This allusion originated in Luoyang during the Three Kingdoms period.

At that time, the Wei army entered Sichuan, and Liu Chan, the queen of Shu, surrendered and was sent to Luoyang. Sima Zhao granted him the title of Lord Anle and granted him a residence, monthly expenses, and hundreds of servants. To express his gratitude, Liu Chan came to express his gratitude. Sima Zhao then held a banquet in honor of him and entertained him with singing and dancing. When the music of Shu was played, the old officials of Shu recited the sadness of losing their country and their family, and all of them burst into tears. But Liu Chan was indifferent and laughed calmly. Seeing this, Sima Zhao asked Liu Chan, "Do you miss Shu?" Liu Chan replied, "This place is very happy, and I don't miss Shu." However, his old minister heard this and quickly found an opportunity to whisper to him. : "Your Majesty, if Sima Zhao asks you again later, you can answer with tears: 'My ancestors' graves are far away in Shu. I miss them every day!' In this way, Sima Zhao can let your majesty return to Shu." "After Liu Chan heard this, he kept it in mind. When the wine was half drunk, Sima Zhao asked again. Liu Chan quickly learned what Que Zheng taught him, but he was about to cry but had no tears. After hearing this, Sima Zhao said, "Hey, how come these words sound like what Chu Zheng said?" Liu Chan was surprised and said, "What you said is absolutely right!" Sima Zhao and the ministers on his left and right all laughed. Seeing how honest Liu Chan was, Sima Zhao never doubted him again. Liu Chan spent the rest of his life happily in Luoyang, and passed down this hilarious allusion of "I don't want to miss Shu".
