There seems to be, I can't remember, I saw it in Yi Zhongtian's Pinren Record before. It's the chapter about Cao Cao. We all know that Cao Cao held the emperor to make the princes, but Yi Zhongtian's point of view is that the Han Emperor was the happiest in Cao Cao's life. For comparison (because Emperor Xian of Han Dynasty was also held hostage by others), it seems that he had the experience of drilling a dog hole.

Because I borrowed this book from the library, I can't tell you exactly.
