After graduating from Taipei Japanese Junior High School, he enrolled at English-based Taipei American School, which enabled him to converse in English. While he was studying there, he began doing television commercials and decided to quit school to pursue a singing and acting career. He is multilingual, fluent in Mandarin, Taiwanese Hokkien, Japanese, and to lesser degrees in Cantonese and English. Taiwanese was the first language he spoke while growing up in Taiwan.
