An ethnic culture research worker in Funing County, Yunnan Province, China, has come across an old Zhuang book of songs. What makes this manuscript particularly interesting is that the songs are written down not in a regular script but rather in something similar to Naxi pictographs, i.e. pictures that serve as mnemonic references to the text rather than as real pictographs or real writing.
The article I read on this is a little vague, so I’m hoping someone can come up with some images of the manuscript or a more scholarly source.
