Chinese sign language alphabet
Sign language can represent 10 numbers and 26 commonly used letters, as well as letter combinations commonly used in Chinese, including, CH, SH, ng, etc. Let every word spoken by ordinary people be accurately expressed in sign language without ambiguity.
However, common words in daily life, such as "hello", "goodbye", "good morning" and "sun", still have special sign language words to express them quickly. Only when people's names, place names and technical terms are difficult to express, will standard sign language be used to express them.
In addition, when encountering the problem of sign language dialects, that is, when different schools teach deaf people different sign languages, we can also compare them with standard sign languages.
