在很久以前，有一位非常贤明的君主，他的名字叫尧。
当尧年纪大了的时候，他决定把自己的位置让给一个叫做许由的有才能的人。
但是，许由拒绝了这个提议，并对尧说：“尊敬的国王，您已经做得很好了，我没有什么可以做的。你看，小鸟在树林里筑巢，它们只需要一根树枝；小老鼠去河边喝水，即使河水再多，它们也只会喝到足够为止。所以，我不需要这么大的天下。而且，如果厨师不愿意做饭，主祭人也不能代替厨师去做饭。同样，我也不能代替您。”
因此，“越俎代庖”这个成语就从这里出现了。
它告诉我们，每个人都有自己的职责和任务，我们不应该超越自己的职责，去做别人的事情。
Long, long ago, there was a very wise king named Yao.
When King Yao grew old, he decided to give his position to a talented man named Xu You.
But Xu You refused the offer and said to King Yao, "Respected King, you have done well. There is nothing for me to do. Look at the birds building nests in the forest, they only need one branch; the mice go to the river to drink water, even if there is a lot of water, they will only drink enough. So, I don't need such a big world. And, if the cook doesn't want to cook, the master of ceremonies can't cook instead of him. Similarly, I cannot replace you."
So, the idiom 'taking over someone else's job' came from here.
It tells us that everyone has their own duties and tasks, we should not exceed our responsibilities, and do other people's things.
