pǔ tōng huà (English spelling) putonghua

…One character, one sound, one meaning, etc., so it is safe to say that from the earliest period of Chinese writing, one Chinese character roughly corresponded to one syllable in this language. Taking the modern Chinese standard pronunciation called 〈Pǔ tōng huà〉 as an example, and based on the orthography based on 〈Chinese pronunciation (heiyon)/pinyin formula〉 (the pronunciation is correctly pronounced hinyon), all of these (C)(M)V(C/V)/T elements exist in biao ³ 〈table〉, suan ⁴ 〈calculation〉, etc., where b‐, s‐ are the first (C), ‐i‐, ‐u‐ are (M), ‐a‐ is the next V, and the former ‐o and the latter ‐n are (C/V). The numbers 3 and 4 are T, which represents a tone, and the previous table shows that when the whole is divided equally, with the lowest pitch being 1 and the highest being 5, it forms a curve roughly equal to 214, while the following calculation shows that it is pronounced in a curve equal to 51.
