First, the time span of ancient poetry is long. Chinese civilization has a long history, and ancient poetry has been accompanied by the inheritance and continuation of this ancient civilization. Due to the long time and cultural changes, the form and meaning of Chinese characters have changed, and the difficulty of textual research will increase with the length of time.
Second, the infinite spatial span of the content of ancient poetry further strengthens its profundity. From the aspects of style, elegance, praise, fu, comparison and xing, the Book of Songs has opened up groups, views, xing and resentment from different angles. Involving all fields and categories of people's lives at that time.
Later, with the changes of history and the continuous development of culture, more and more ancient poems were expressed and covered. As a unique literary form, ancient poetry itself is constantly enriching and changing from form to content. Formally speaking, ancient poetry experienced four-character, five-character and seven-character rhythms (and a few six-character rhythms), and then it formed a standardized modern poetry in the early Tang Dynasty. From the content, the expressions of various emotional things, such as homesickness, nostalgia for the past, expressing one's wishes in tangible ways, sending people away from home, paying homage to others and so on, are all-encompassing and endless.
Third, from the reader's point of view, a person's knowledge, compared with knowledge handed down for thousands of years, is tantamount to a drop of water compared with the sea. As Mencius said, "My life is limited, and so is my knowledge." Therefore, it is normal for readers, as aesthetic individuals, to feel deeply in the face of the vast ancient poetry culture.
In short, we should be proud and happy to have such a profound and splendid ancient poetry culture. Moreover, in addition to feeling, we should also improve our sense of responsibility. In order to inherit and carry forward the excellent traditional culture, we should learn more from the precious heritage of our predecessors, beautify our lives with cultural nutrition, serve the society and highlight the unique brilliance of Chinese civilization.
