I have learned a lot when I went to Museo Negrense most especially about Mangyans. Mangyan, the generic name of the eight indigenous groups found in Mindoro island, comprises about 10% of its total population.
They live through farming, selling of native products, hunting etc. Products they made are beads, and bamboo produce primarily. There is also a myth about the Mangyan having a tail. In reality there is none, but only a piece of cloth dangling on their back.
The eight tribes, are Alangan, was derived from the name of a river and mountain slopes in the upper Alangan valley; Bangon, found along the Bongabon river called Binagaw, have their own culture and language different from the other six major tribes. Tau-buid which is known for their pipe smoking that begins at a very young age. And their standard dress is loin cloth, for both men and women; Buhid, which are known as pot makers; Hanunoo practice swidden farming, which prevented land deterioration. Tadyawan uses kaingin farm system for their subsistence; Iraya, a type of mangyan having a curly deep wavy hair and dark skin but not as dark as the negrito; and the Ratagnon, found in the southernmost part of the municipality of Magsaysay in Occidental Mindoro. Mangyans also have their own system of writing called Mangyan syllabic script, that is being used on how the word is pronounced, not as how the word is being spelled. They also make artifacts without the use of modern technology, being delicately done by their skillful hands and creative thinking.
Though their culture is much more different from us, we should respect them as they are still Filipinos.
