What does it mean to add simple strokes to ancient poems?

The simplest and quickest way to visualize a poem is to stick figure. Its characteristics are simple graphics, vivid images and humor. As the saying goes: "There is a picture in the poem, and there is a poem in the picture." In junior high school poetry teaching, an ancient poem is often accompanied by illustrations in the textbook, which basically shows the artistic conception described by the ancient poem. But this can only give students a holistic and vague perceptual knowledge, which is not very helpful for students to understand and recite ancient poems.
