"Chinese characters are
logographs used
to write the Chinese languages and others from regions historically influenced by
Chinese culture. Chinese characters have a documented history spanning over three millennia, representing one of the four independent inventions of writing accepted by scholars; of these, they comprise the only writing system continuously used since its invention. Unlike letters in alphabets that reflect the sounds of speech, Chinese characters generally represent
morphemes, the units of meaning in a language. Writing a language's entire vocabulary requires thousands of different characters. Characters are created according to several different principles, where aspects of both shape and pronunciation may be used to indicate the character's meaning."
In Taiwan traditional Chinese characters are used, while the mainland uses simplified characters. The difference in complexity is noticeable even to me, a non-Chinese speaker.
