Hanoi Sign Language

Hanoi Sign Language is the deaf-community sign language of the city of Hanoi in Vietnam. It is about 50% cognate with the other sign languages of Vietnam, and its vocabulary has been extensively influenced by the French Sign Language once taught in Vietnamese schools for the deaf.
