The fascinating story of Noto Sans Nüshu:

In this context, women created in their parallel world a creative way full of practical sense to communicate between each other despite distances. They kept the script evolving through times, using it in many ways and ended up creating a culture of their own, aside the culture of men. This script is an wonderful example of creativity resulting from a social separation between men and women, and at the same time a strong solution to a problem: a missing connexion with cherished people and more.
