The term "Taiwanese people" has various interpretations. It may generally be considered the people living on the island of Taiwan who share a common culture, ancestry and speak Mandarin, Hokkien, Hakka, or indigenous Taiwanese languages as a mother tongue. Taiwanese people may also refer to the indigenous peoples of the areas under the control of the Government of the Republic of China since 1945, including Kinmen and Matsu Islands that collectively form its streamlined Fujian Province. However, the inhabitants of Kinmen and the Matsu Islands themselves may not consider the "Taiwanese" label to be accurate as they are a part of Fujian and not Taiwan. They have a distinctive identity from that of the Taiwanese; viewing themselves as Kinmenese or Matsunese, respectively, or as simply Chinese.
