The implementation of this standard has effectively solved the desire of sign language users of hearing-impaired people to express the national anthem in a standardized, unified and serious manner when playing the national anthem for many years, and will make the hearing-impaired people fully and accurately feel the national spirit expressed in the national anthem, call for deep patriotic feelings, and promote the prosperity and development of cultural education for the disabled in China. ?
Different from language:
The difference between sign language and language mainly lies in pronunciation and whether deaf people think with gestures. Linguists believe that sign language is a symbol, not a language, according to the phonetic properties of language; Deaf education experts, special educators and deaf people themselves believe that sign language is also a language, a branch of language and a special language form from the perspective of language attributes.
However, sign language can't absolutely correspond to written language, and the written language of deaf-mute people is restricted by sign language, so it can't form a correct written language. Although sign language can't be used as a language in the full sense, its linguistic attributes indicate that sign language should be one of the language types.
