求翻译：很久很久以前，凤凰只是一只很不起眼的小鸟，羽毛也很平常，丝毫不象传说中的那般光彩夺目。但它有一个优点：它很勤劳，不像别的鸟那样吃饱了就知道玩，而是从早到晚忙个不停，将别的鸟扔掉的果实都一颗一颗捡起来，收藏在洞里。是什么意思？

A long, long time ago, Phoenix is only a very small bird, feathers are very common, nothing like as dazzling as the legendary. But it does have one advantage: it is very diligent, as other birds do not eat know to play, but kept busy from morning till night, fruit will throw the other birds are picked up one by one, collecting in the cave.
