KK Phonetic Alphabet of Xie Mengyuan

First of all, we should know that phonetic symbols are used to help pronunciation, so symbols are not very important. 48, 44, 4 1 are all the same, but the editor needs to make individual deletions, so it will not affect English learning. International phonetic symbols have also changed in recent years, which does not affect the learning of English pronunciation, so learning that set of phonetic symbols is the same, but you should be familiar with the phonetic symbols in the dictionary. For example, Oxford generally uses KK and Jones phonetic symbols, which are a little different from international phonetic symbols in terms of standards and do not affect pronunciation.
