Express Enjoyment Without Indulgence and Express Grief Without Excessive Distress
快乐而不放纵，悲哀而不伤身。原是孔子对于《诗经·周南·关雎》中有关青年男女爱情描写的评语，后世儒家将其作为倡导诗歌及其他文学作品中正平和、情理谐和之美的基本规范与评价标准。这一术语与儒家提倡的中庸思想相一致。近现代以来，其思想内涵也因受到时代潮流冲击而不断更新。
This is what Confucius said of the description of love between young men and women in the poem entitled “Guan Ju” in “Ballads of Zhounan,” The Book of Songs. Later Confucian scholars regarded this as a basic requirement for poems and other literary works to advocate impartiality, peace of mind, and harmony between emotion and reason, making it a criterion for evaluating literary works. Its connotation is in accord with zhongyong (the golden mean) of Confucianism. In the more recent history, the connotation of the term has been continuously renewed to keep pace with the times.
