Lesson one from Popular Dongba Script 通俗东巴文. This textbook is apparently the book that kids use when learning Naxi and Dongba script as an extra-curricular class in Lijiang. Naturally, it's not a popular class - but hey, if nobody learns it, then it's gone for good...
Have a listen (the first three characters that make up the title are not read out).
It's a short reading from a Dongba scripture: Heaven and earth. Written from left to right.
The translation should go something like this:
"In the high heavens, the stars appear;
the stars shine bright today.
On the broad earth, the grass grows;
the grass is green today."
