To what extent should a poem be written to be a good poem? I think a poem with true feelings is a good poem that can really write what you want to express. A good poem needs to give people a certain degree of psychological shock, give people a buzz, let readers feel the thoughts and feelings that the author wants to express, and extend a deeper connotation in the poem that even the author has not designed. In a word, emotion is the first element of poetry, and the profundity of words is a necessary condition for poetry writing.
Hehe, it's just my little knowledge.
