Dingfengbo is a poem about love, which has a distinctive folk flavor and is the representative work of Liu Yong's "slang words". In the tone of a young woman (or prostitute), this word expresses the lovesickness after leaving her lover and depicts the image of an innocent young woman.
It is said that Schumann, a famous poet in the Northern Song Dynasty, is very familiar with this word and has his own different views. Once, Liu Yong went to see Yan Shu. "Gong Yan said,' Does Xian Jun compose music?' Sanbian said,' Just like Xianggong, you can also compose music.' Gong said: "Although I wrote a piece of music, I never said,' I sat on that colored line carelessly.' Liu then retired. "(see Zhang Shunmin's Painting Spectrum), it seems that the content and expression of the word Liu Yong were unacceptable to the literati at that time, and its description of love and young women's inner activities was straightforward, hot and bold. Use a pen to be pungent and undisguised. This is quite different from Schumann's elegant words, which are implicit, harmonious, calm, graceful and rich. However, as long as the word Ding Fengbo is comprehensively analyzed, it is difficult to draw the conclusion of "vulgarity" and "revealing pornography".
