It was especially difficult to find anything about frogs like the emerald green tree frog, which live only in very circumscribed areas. Since he was an outsider to biology, his only option was to start from scratch. He gave himself an assignment: Before rushing out to photograph the frogs, first find them, observe them, and understand them.
特別是翡翠樹蛙、諸羅樹蛙等分佈地區狹窄的種類，更難尋找，他又並非生物界的圈內人，只能從零開始，他給自己定下目標，不急著拍照，先去尋找與認識青蛙。
