Wang Fu-chang is from Tachia in Taichung County, and had always spoken Taiwanese at home. But when he went to elementary school, the rule was that you had to speak Mandarin, or else you had to wear a warning sign saying "I don't speak dialect," or pay a fine.
王甫昌是台中大甲人，自小在家中說閩南語，上小學後，學校規定要說國語，否則要掛「我不說方言」的警告牌，或者罰錢。
