Why does Cantonese sing so well, while other dialects sing so badly?

Because Cantonese can be completely read in written language-that is, the pronunciation of every word does not conflict with orthography.

Cantonese, like Mandarin, all commonly used Chinese characters have "pronunciations".

This advantage, Cantonese can be equally divided with Putonghua, although according to the number of more than 40,000 Chinese characters in the Chinese Dictionary, Cantonese still cannot be pronounced with Putonghua PK in writing.

But if you master about 4000 words, you will have good oral expression ability, that is, in the limited PK, Cantonese and Mandarin can definitely be 5: 5.

This is impossible for seven other dialects, such as two other Cantonese, Hakka and Chaoshan dialects. First, some written words can't be pronounced. Second, even if there is, it may be "different sounds in ten miles"-in this case, it is "zero existence" in Cantonese.
