What does Confucius mean by "being happy with poetry, standing on ceremony and being happy with things"?

Poetry is used to express the will, promote the individual's consciousness of seeking goodness and benevolence, realize people's self-reliance with courtesy, and finally realize the cultivation of the highest personality under the influence of music education.

Origin: In the Analects of Confucius, Confucius put forward three aspects of his education: poetry, etiquette and music, and pointed out their different functions. It requires students not only to talk about personal accomplishment, but also to have comprehensive and extensive knowledge and skills.

Extended data:

Music is an important carrier of civilization inheritance and an important embodiment of national cultural spirit. According to the Analects of Confucius, Confucius' students preached enlightenment in the form of string songs when they toured the butcher in Wucheng.

Although there are many records about ancient music forms and music thoughts in ancient books, we have no chance to know the ancient music such as Shao and Wu, which Confucius admired, and the huge amount of ancient music since the Millennium. Even if the Tang Daqu found in Dunhuang was written on the music score, it is hard to say that it can be correctly interpreted today because of scribbling and other reasons.

In this way, music books recorded by Miyachi notation since the Song and Yuan Dynasties have become extremely valuable materials for us to understand ancient music. Theoretically, these music scores belong to the category of traditional Chinese opera philology. They inherited the vocal music poems of the Tang and Song Dynasties, and absorbed the elements of drum words, Zhu Gong tunes, singing and stepping, folk songs and foreign music. After long-term polishing and processing, they formed a unique musical form.
