In addition to the meaning, disyllabic words have another feature, that is, the change between tones in phonology. In Mandarin, the rules of level tone and tone are also obvious. For example, the word "autumn" in "Shepherd" corresponds to the word "Shu" in "Shu", the former is unvoiced and the latter is uplifted. And this arrangement of flat tones and tones also makes the whole disyllabic word more beautiful.
Although disyllabic words have their unique forms and phonetic features, it is not easy for ordinary readers to understand and appreciate them. You need to have a certain reading ability and cultural background in ancient Chinese to understand its beauty smoothly. China's modern poetry also has similar elements such as rhyme and rhythm, which can be regarded as the continuation and development of traditional poetry.
