Why does Li Yu have a pure heart?

I think people who like Li Yu are interested in his childlike innocence. The so-called "childlike innocence" means "frankness" and "true temperament" in plain English. The writing style is not eclectic, and the words are not carved, and the emotional expression is casual. Li Yu's ci is a unique embodiment of "truth". There are historical comments as evidence: the rich are rich words, and the sad are sad words. Every sentence is untrue, every sentence is not handsome. -Liu's History of Ci is only a personal opinion. If you have any questions about Li Yu, I'd be happy to answer them.
