"Zhuyin fuhao, often abbreviated as zhuyin and colloquially called bopomofo, is a phonetic system for transcribing Chinese.
Consisting of 37 characters and four tone marks, it transcribes all possible sounds in Mandarin.
Although phased out in Mainland China in the 1950s, this system is still widely used as an educational tool and Chinese computer input method in Taiwan."
