There is a book about poetry appreciation. Dilution, elegance and so on?
For the book of poetry appreciation, I first recommend reading Wang Guowei's Poems on Earth. I watched it twice, and I got something every time.
Then "Cang Hua" is also good, and some modern people write poems for appreciation and compile them into a book. But personally, in addition to exquisite binding and good feel, the rest are just idle books to kill time.
