And they have been successful in this approach. For example, since coming on the market in 1994 The Trees of Taiwan has sold 70,000 copies. And the work 365 Days of Taiwan Wildflowers, released in 1997, has sold 40,000 copies, despite the fact that it costs NT $ 1300 for the two-volume set.
果然，皇天不負苦心人，大樹出版的《台灣賞樹情報》自一九九四年上市以來，已賣了七萬本；一九九七年出版的《台灣野花 365 天》，上下兩冊一千三百元，賣了四萬本，都名列長銷書。
