I have never heard of Dongba language, the last living pictographic language till Kasia mentioned it on our way to Lijiang in Yunnan province. It is written language of the Naxi people, ethnic minority concentrated around and in beautiful city of Lijiang, containing around 2000 characters looking more like a nice pictures.
The best place for interacting with Naxi people wasn’t in Lijiang, but in nearby small village called Baisha. We arrived in the morning; people were already on the streets building or reconstructing their houses, selling some stuff or waiting for visitors that got here searching for nice quiet place to walk around and enjoy rural life.
