Nüshu is a female-specific writing system, circulated in Jiangyong County, Hunan Province, China. Women in Jiangyong have been using nüshu to write biographic laments, make sworn sisters, and release sentiments of misery. This script has been silently practiced in this area for many hundred years. In that allegedly dead script still lives a woman who can write in nüshu – He Yanxin.
