What are the beautiful works in China's classical literature?

Six Chapters of a Floating Life, A Dream of Red Mansions and Memories of Tao Anmeng.

Six Chapters of a Floating Life was copied by Shen in Qing Dynasty, which is a form of life record. The heroine in it is my favorite character in China history (or cultural history). The description of husband and wife's life is simply not so good. I always feel that the literati in the Qing Dynasty are so single-minded. After reading Six Chapters of a Floating Life, I thought there was a loquat tree poking tears in that sentence, but I prefer the literati of the Qing Dynasty. In short, I strongly recommend that classical Chinese is not difficult to understand.

Everyone in A Dream of Red Mansions should know that the scenes described and the relationship between characters are very grand, involving all kinds of entanglements and the background of the times. It's complicated. Relatively speaking, the small family told in six stories and the big family told in a dream of red mansions are two different feelings, and the only thing they like very much is the love between men and women.

Tao An Meng Yi was written by Zhang Dai, a scholar in the late Ming Dynasty. When I was in high school, I read the preface of Tao An Meng Yi and found it very interesting. However, this is prose, mostly recalling the author's life experience, but the writing is elegant and must be recommended.
