Taiwan is a country colonized by various regimes over the past four hundred years. The research first adopted the narrative inquiry-an autobiography on my journey to find my Taiwanese identity and mother tongue loss. Secondly, a phenomenological study on three Taiwanese families was conducted to secure an in-depth complex understanding on the scope and extent of the language loss phenomenon in Taiwan, of the thoughts and feelings about losing mother tongues, of the role of political power, the colonial history and other sociocultural contexts in the language loss phenomenon in Taiwan. Ten features and eleven themes were identified in this study. The political power and colonial history are important factors of mother tongue loss among my three participant families.
