Sign language, Braille promoted

China will incorporate a standard sign language and Braille by 2020 in all the country's schools that serve students with special needs, as well as in the public service sector, to help those with disabilities improve their level of education, an official of the China Disabled Persons' Federation said.

Cheng Kai, deputy director-general of the federation, said on Thursday that regional differences in sign language and the lack of tonal marks in Braille have created problems in communication for people with hearing, vision and speech impairments.

To ensure the language rights of the group, as well as to facilitate education, the federation will strive to promote official standards for sign language and Braille in accordance with a five-year plan.
