Chang Huei-fen says that originally Big Tree put out roughly equal numbers of translated books and locally focused books. But they later found: "Translated books got lost in the sauce once they hit the market, because there are too many similar books and the market can't digest them all; it is difficult to set yours apart from the others. So in fact translated books were our weak link."
張蕙芬說，大樹的翻譯書與本土自然系列，原本維持各一半的比例，後來發現「翻譯書一上市就被淹沒在書海中，因為同類型的書太多，市場難消化，也很難凸顯特色，反而是最弱的一環。」
