There are in Tibet Autonomous Region 190,000 disabled persons,including more than 30,000 who are deaf-mutes or are hearing impaired.In the Tibetan language,a word is often expressed with different signs.This poses a serious handicap for communication and exchanges among Tibetan deaf-mutes and their effort to participate in social activities.The ongoing research and development of a Tibetan sign language is expected to get rid of that handicap and allow Tibetan deaf-mutes to lead a normal life.
