Deaf people who don't go to school sometimes sign language, but it is not standard. This comes from body language in life and is also the result of communication and learning with deaf people.

Now there are sign language learning materials on the internet, and the key is to communicate with the deaf. There is a sign language corner near the Wuhan River, where people communicate every weekend. It is suggested that sign language corners be set up all over the country to help deaf people, so that they will no longer be lonely and encounter communication obstacles everywhere.
