Hangzhou’s First “Sister Sign Language” real-time online translation system was launched at Jietansi Lane Community Service Center, Tianshui Subdistrict, Gongshu District yesterday morning. Sister Sign Language is an IP created by Hangzhou Municipal Disabled Persons’ Federation in 2010, inspired by MAO Donglai, a-hearing impaired girl, aiming to popularize sign language and show the spirit of the disabled to the public in a better way. Now a sign language volunteering service team of more than 40 members has been formed and Hangzhou Sister Sign Language Barrier-Free Communication Service Center has been established.
