Re: Chinese alphabet
In the spoken chinese language, each character is connected with a syllable of the language. In the different chinese dialects (at least 8 main dialects) the pronunciation of the characters is different but the meaning of the chartacters is the same and a north chinese (speaking mandarin dialect) can read a newspaper in guangzhou (cantonese dialect) without problems but will not be able to talk to another person who only speaks cantonese.
