Answer:
The Ambahan is a literary product and poetic expression of the Southern Mangyans of Mindoro, Philippines. Although there are about seven different ethnic groups living in Mindoro, collectively called the Mangyans, these groups are quite distinct from each other as to language, customs, and way of living. Only the ethnic group living in the south of Mindoro, roughly comprising the areas within the municipalities of Bulalacao (San Pedro), Mansalay, Oriental Mindoro and San Jose, Occidental Mindoro, claims the name Mangyan as the descriptive title of their tribe. To stress their point, they might add the epiteth: "Hanunuo" Mangyan, that is, a "truly, real, genuine" Manygan.
