Zhuyin Fuhao, often abbreviated zhuyin and colloquially called bopomofo,In Chinese, "bo", "po", "mo" and "fo" are the first four of the conventional ordering of available syllables. As a result, the four syllables together have been used to indicate various phonetic systems. For Chinese speakers who were first introduced to the Zhuyin system, "bopomofo" means zhuyin fuhao.
