First of all, before we have Chinese class, we need to preview the ancient poems we need to learn in advance, because ancient poems are classical Chinese after all, and you certainly don't understand them very well, just in the first day of junior high school. When you preview, you need to know what this ancient poem is about, whether it is about things, people or scenery. You also need to know what style this ancient poem you preview is, whether it is pastoral style, romanticism or frontier poetry. Next, after you know this, you need to understand the poet, the poet's fear story, and the background of the poet's time. If you know the information of these poets, you will not only learn this ancient poem, but also learn all the poems of this poet in this period.
Another point is that you need to listen to the teacher carefully in class. The teacher will tell some allusions in class, which you can't do by previewing yourself. The study of ancient poetry is very long. Need the accumulation of knowledge.
