At that time in Taiwan many people followed fashion by wearing the Japanese kimono. But Chang Chi-lang, practicing medicine in Fenglin, usually wore a Chinese long robe or a western-style suit and never a kimono or wooden sandals, making quite clear his opposition to the imperial occupation. He never forgot he was Chinese.
