Analysis:
Because poetry is short and pithy, it is often written on manuscript paper with only five or six words in one line. Therefore, it is impossible to write 800 words in a general composition. (especially the exam composition grid is limited, and teachers usually don't encourage students to write poems. However, from my personal point of view, such restrictions have seriously suppressed the literary creativity of young people in China. So that "Li Bai" and "Du Fu" can't "let a hundred schools of thought contend" in this era!
