Cantonese Braille is a Cantonese language version of Braille in Hong Kong. It is locally referred to as "tim chi", dot character, or more commonly, "tuk chi", raised character. Although Cantonese is written in Chinese characters, the Cantonese Braille is coded by purely Cantonese phonetics, with some special codes for Chinese punctuations and numerals.
Cantonese Braille represents the sounds of the language rather than the characters. It is written from left to right in horizontal lines running from top to bottom. Each syllable is made up of three Braille letters: one for the initial, one for the final and one for the tone, though the tones marks are rarely used. Words are separated by spaces.
