Cantonese Pinyin (Chinese: 常用字廣州話讀音表:拼音方案) and also known as (Chinese: 教院式拼音方案) is a romanization system for Cantonese developed by Yu Bingzhao (余秉昭) in 1971, and subsequently modified by the Education Department (merged into the Education and Manpower Bureau since 2003) of Hong Kong and Zhan Bohui (詹伯慧). It was used by Tongyin zihui (同音字彙), Cantonese Pronunciation list of Chinese Characters in Common Use (常用字廣州話讀音表), Dictionary of Standard Cantonese Pronunciation (廣州話正音字典), and List of Chinese Characters in Common Use for Primary education (小學中文科常用字表). It is the only romanization system accepted by Education and Manpower Bureau of Hong Kong and Hong Kong Examinations and Assessment Authority.
Note that the formal and short forms of the system’s Chinese names mean respectively “the Cantonese Pronunciation list of Chinese Characters in Common Use romanization system” and “the romanization system of the Hong Kong Education and Manpower Bureau”.
