Is sign language (sign language) universal?

It is not universal. Every country creates sign language according to its own language habits and thinking habits. Even as far as I know, the mainland and Guangdong are different. The following are some news about Chinese sign language and world sign language:

China has a vast territory, and the popular gestures are very inconsistent, which is not conducive to the social communication of deaf people. 1959, the China Association for the Blind and Deaf compiled and revised the Draft of General Sign Language for the Deaf, and submitted it to the former Ministry of Internal Affairs, the Ministry of Education and the China Language and Character Reform Commission for approval. Four series of * * * 2000 gesture patterns have been published, which are well received by the deaf.

Welcome to visit. Most of the four series of essays published during the Cultural Revolution were lost, which interrupted the trial and promotion work. 13 August 1979 to13 August 1979, the preparatory group of China Association for the Blind and Deaf held a national symposium on sign language work, which discussed and formulated 430 unified sign language gestures for deaf people and tried them out nationwide. 1982 10 6 18 From June 2 6, the second symposium on sign language work was held in Beijing, and 640 sign language gestures for deaf people were discussed and formulated. The Ministry of Civil Affairs, the Ministry of Education and the China Language Reform Commission jointly issued a notice, which was put into practice nationwide.

Sign language is always inconsistent, and different communication areas have different sign language expressions.

There are differences between schools, regions and north and south, which affect mutual understanding. However, once the local sign language becomes a habit, it is quite stubborn, and it is difficult for them to seek common ground while reserving differences. Like the situation between dialects, there are similar problems in popularizing universal sign language for the deaf. At present, there are more than 3,000 words * * * in common sign language, most of which are used customary gestures, a few of which are originally modified customary gestures, and some finger gestures mainly used for names, places and function words have been added. In addition, some international gestures of country names have been transplanted. "Universal sign language" not only provides unified and standardized sign language graphics, but also makes sign language into written form, but it still needs long-term and sustained efforts to promote universal sign language based on Putonghua nationwide.

Due to the super-dialect or even super-linguistic nature of sign language, the International Association for the Deaf and the Deaf has been able to produce 1500 sign language, which is one of the working languages of international conferences.
