Deaf people are usually divided into congenital deaf-mutes and acquired deaf-mutes for the following reasons:

1, congenital deafness: It is mainly due to genetic factors, and children will be deaf at birth. When you grow up, if you find that you can't learn a language, you may become deaf.

2. Acquired deafness: Before and after learning a language, children who are deaf due to trauma or ototoxic drugs will also have language learning disabilities, thus forming deafness. Usually, because they are deaf, they can't get in touch with the language, especially before learning it. Deaf people can't receive effective information when learning a language, so they can't learn a language, which leads to deafness. After the human body is deaf, it is likely to develop into a deaf-mute person.
