First, poets are good at writing scenes from many angles, such as mountains and forests; Close-up shots, such as bamboo and walls; Looking up, such as "turning over a blank bird"; Have a bird's eye view, such as "According to Water Red"; Have hearing, such as "Chaos Cicada"; There is also a sense of smell, such as "fragrance". Such multi-angle scenery description makes the scenery look so layered that there are pictures in the poem;
Second, there are feelings in the scene, such as "cicadas" and "rotten grass", which are not only objective scenery, but also contain the poet's depressed mood.
