Indecipherable Ancient Books Found in Chongqing

Neat Story on some really old books. The Tujia have been known as an ethnic minority with its own spoken language but without a written language. Yet a succession of ancient books in the same written language have been found in the Youyang Tujia habitation straddling the borders of Hunan, Hubei, Guizhou Province, and Chongqing City. For the past two years none have been able to read the ancient books.
