Chinese characters are logograms used in the writing of Chinese and some other Asian languages. In Standard Chinese they are called Hanzi (simplified Chinese: 汉字; traditional Chinese: 漢字). They have been adapted to write a number of other languages including: Japanese, where they are known as kanji, Korean, where they are known as hanja, and Vietnamese in a system known as chữ Nôm. In English, they are sometimes called Han characters.
