Speaking first of the owners and operators, Taiwan is a small place where business information gets around quickly. When people see somebody making a lot of money running an amusement park somewhere, they want to open one, too. It's hard to come up with a design of your own, and it won't necessarily make money.
從業者方面來說，台灣地方小，商業情報很靈通，看到別人在某處開了一間遊樂園很賺錢，我也來開一家；動腦筋自己設計一個比較辛苦，而且不一定會賺錢。
