If it is a language then it should have better support and recognition internationally. I have looked at some linguistic aspects of Korean, Japanese and old Vietnamese (before Korean and Vietnamese phoneticise their languages) in the use of Hanzi, Hanja in these languages. In a similar way Cantonese use the Hanzi writing system. However the way Cantonese is spoken is not written down in the same way (a lot of word simply don't have a Hanzi word for it and the sentence construction is different since the Chinese language has little grammatical notation when compared with German especially). The same for Hakka, Chiu Chau etc...However in French, German and English you say it as you write it (nearly). In Europe when I look at the Indo-European languages , German notably, there is High German, Low German, Swiss German, Luxembourgish, Dutch, Flemish, Danish.. many of these Germanic variation are all languages in their own right. Likewise Cantonese should have its own writing system and hence can become an official language. How do you think? Should the Hanzi writing character set be expanded to include Cantonese, Hakka, ChiuChou..etc?
