Why do I get very low marks on Chinese poetry appreciation, and I still can't do it after reading many methods?

First of all, you should read the poem roughly and feel the general artistic conception, but this should come from the feelings in life. Secondly, you should look for a deeper understanding from the side, such as the side meanings reflected by some words, and then you can apply the general format, but you can't write too digressively. You should also look at the scores and answer the questions separately.
