Sign language learning facilitates communication between hearing-impaired people and hearing-impaired people, and between hearing people and hearing-impaired people.

Sign language learning is one of the prerequisites for working in deaf education.

Deaf educators must use sign language in educating the minds of the hearing impaired, implementing education and teaching plans, organizing teaching, and helping the hearing impaired learn science and culture.

Using sign language to organize school meetings, class meetings, and various activities, and proficiency in sign language directly affects the effectiveness of education and teaching.

The world of sign language is as colorful as that of spoken language.

The sign languages that are used in various places belong to different language families, groups, and branches according to their origins, and have their own vocabulary, grammar, and orthography for transcribing the spoken language.

However, the genealogical affiliation of sign languages is not necessarily related to the local spoken language.

For example, British and American languages share a common language, but the prevailing sign languages are very different and belong to different language families.

Thailand and the United States do not speak the same language, but the prevailing sign languages are very similar and belong to the same language branch.

This means that American Sign Language and Thai Sign Language are even more interchangeable than British Sign Language.

American Sign Language has a different base vocabulary compared to British Sign Language: the core vocabulary of British Sign Language is mainly of British origin, while much of the core vocabulary of American Sign Language evolved from French Sign Language.

Nowadays, we promote harmony among people. The deaf community is a vulnerable group in society.

Although the deaf community has received care and support from the Party and government and all sectors of society, their status and life have improved to a certain extent.

However, due to their own defects and secular prejudice, it is still difficult for deaf people to truly achieve equality and participate in society.

In order to better help deaf people to be employed and self-sufficient, to achieve their goal of equal participation in socialist modernization, to contribute to economic construction, and to achieve the best integration with mainstream society.

We hear people should learn more and learn more sign language.

To achieve mutual communication and exchange between the deaf community and the hearing people.

Language is a part of culture and plays an important role in it.

It not only contains the history and cultural background of the people, but also contains the people's view of life, way of life and way of thinking.

The cultural context of sign language is the culture of the Deaf.

Because of their unique language system, Deaf people naturally group together to form a community and share experiences, interests, and survival skills with each other, which in turn leads to similar patterns of behavior and Deaf culture.

Culture emerges from descent, language, and habits, with the language being the most influential.

Different languages produce different styles of the culture and deeply determine the content of that culture.

Deaf people use sign language as their mother tongue, and with hearing impairment, they are unable or difficult to receive sound stimulation.
