These people live in the mountainous areas because dominating colonizers were in Taiwan for over 380 years. Outsiders have killed the indigenous people, burned villages, and forced them to move as the colonizers claimed more and more spaces. Some such colonizers were the Dutch, Spanish, Japanese, and Chinese. The outside rulers imposed their own education systems on the indigenous people, but the most notable influence came from the Kuomintang era, where Taiwanese people were forced to use Mandarin and where children were punished at school if they used their own indigenous language. This forced the original Taiwanese people to give up their language in order to survive in the new, imposed environment.
