Sidney Lau (Template:Zh, died 1987) wrote a series of textbooks in the 1970s, for teaching western people to speak Cantonese. The textbooks were initially used for teaching western expatriates working in the Hong Kong Police Force and other government bodies. Later the texts were used as a basis for a radio teaching programme for foreigners.
The books introduced Lau's own romanisation system which differs from the Yale system by using superscripted numbers and symbols to indicate the word tones. The system is one of three romanisation systems still in use in Hong Kong.
Despite their age, the books are still very popular being one of the few comprehensive books teaching spoken Cantonese (as opposed to written Chinese and spoken Mandarin, which are significantly different).
