As ordinary people in Taiwan have gradually become more prosperous, keeping monkeys has become fashionable. Perhaps most people don't realize that other countries require people rearing primates to provide them with balls with which to pass the time. The requirements for their welfare are more advanced even than for children--human laws have never stipulated that "parents must buy toys for their children."
逐漸富裕的台灣民眾，流行養猴子，而大部分的人可能不知道，國外規定飼養靈長類動物，必須提供球類供其打發時間，要求比兒童福利更先進；人類的法令可從沒有規定「父母一定得給兒女買玩具」這一條。
