Today I also found some texts that were used to teach the Vietnamese language to ethnic minorities in South Vietnam. This one is for the Cham, but there were other versions for other ethnic groups.
Southern Illinois University played a role in creating these materials.
This text has Vietnamese at the beginning.
And Cham translations at the back of the text.
I particularly like the above two images.
“Má tí về nhà,
“Ba tí về nhà,
“. . . nhưng thầy u ở dâu?!”
