Tsai, who has lived in Thailand and speaks the language, is now studying Indonesian. "All students in the Tamkang Graduate Institute of Southeast Asian Studies are required to study Malay and reside for extended periods in country, so as to learn to view issues from a local perspective."
居住過泰國、通曉泰語，蔡青龍如今開始學習印尼語，「至於在淡江東南亞所，所有的學生都必須學習馬來語、到當地長住，學習從當地的角度來看問題。」
