The reason for this is the following：
Learning ancient poems is to let us know the thoughts of the ancients and learn their noble sentiments. It is also a step-by-step learning process. Only in this way can we continue to climb up and surpass the ancients.
The use of poetry is graceful or vigorous, just like the artistic conception of painting, which makes people feel as if they are there in reading and understanding. The neat specifications and smooth rhymes can be said that the ancestors exhausted their essence and crystallized their works, which can make people feel the beauty in the learning process of ancient poetry, such as bathing in the spring breeze. Of course, in school, you may study because you want to, and you can't start from an independent point of view, which will lead to rebellious psychology. It can't be said that it is a pity of exam-oriented education.
