For deaf-mute children, these four language education methods are indispensable. Speaking and speaking can gain the widest social communication ability, which is the highest accomplishment of deaf-mute language skills. Sign language is the most realistic and urgent means of social communication. Sign language is an auxiliary means to learn common characters (Chinese characters) in Mandarin, have dialogues and improve the quality of sign language. Chinese characters are the key to a comprehensive grasp of China culture. Sign Language Teaching for Deaf-mute Among the four forms of language teaching for deaf-mute, sign language takes priority. An educated person can be illiterate in Chinese characters or a mute who can't speak or see, but he can't help but know sign language. Life needs him to master some kind of sign language to some extent. Chinese characters and sign language are much more troublesome and difficult to learn and apply than sign language, which makes deaf people always communicate with each other by gestures. 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.
