Chinese speech is based on the laws of rhythm, according to which speech cycles in a statement are formed from two, three, four monosyllabic words or polysyllabic words consisting of a corresponding number of syllables. These laws also apply to multi-syllable linguistic units, so rhythmic rules are one of the important foundations of their formation. An important consequence of the rhythmic requirements for the quantitative units of the Chinese language is that the same reference is carried out in speech with the help of a quantitative unit of different composition: one-syllable, two-syllable, etc. The desire for predominantly double-syllable rhythmic groups in speech also leads to a radical transformation of the vocabulary in the language: for many two-syllables a return to the original form becomes impossible, and in Chinese dictionaries of abbreviated words such words are given with the comment “yicihua” ‘has already become a word'. Rhythmic patterns also appear at the level of syntax and grammar. The ability to correctly operate syllabic morphemes plays an extremely important role, both in the creation and in the understanding of the flow of Chinese speech. We suppose that it is necessary to explain to students more specifically the rhythmic rules for choosing quantitative variants of words in Chinese. Indeed, although the theoretical description and explanation of these phenomena has existed for a long time, in practical teaching of the Chinese language in most cases this aspect has not yet been adequately covered.
