History of education
Although there are more than 40,000 Chinese characters in written Chinese, many are rarely used. Studies have shown that full literacy in the Chinese language requires a knowledge of only between three and four thousand characters.
Written Chinese
In contrast to the popular conception of Chinese as a primarily pictographic or ideographic language, the vast majority of Chinese characters (about 95% of the characters in the "Shuowen Jiezi") are constructed as either logical aggregates or, more often, phonetic complexes. In fact, some phonetic complexes were originally simple pictographs that were later augmented by the addition of a semantic root. An example is 炷 "zhù" "candle" (now archaic, meaning "lampwick"), which was originally a pictograph 主, a character that is now pronounced "zhǔ" and means "host", or The character 火 "huǒ" "fire" was added to indicate that the meaning is fire-related.
