很久以前，有一位国王叫梁惠王。
他有一个很会做菜的厨师，大家都叫他庖丁。
有一天，庖丁要给梁惠王杀牛。
他轻轻地用手指摸了摸刀，然后把膝盖靠在牛身上。
只听“咔嚓”一声，牛皮和骨头就分开了！
梁惠王看到了，非常惊讶，问庖丁：“你是怎么做到的？”
庖丁微笑着说：“因为我已经明白了用刀的道理。”
庖丁接着说：“当我刚开始学杀牛的时候，我看到的是整头牛，不知道从哪里下手。但是，经过三年的学习，我开始看到的只是牛的筋骨结构。现在，我不需要看就能感觉到牛身上的骨骼组织，我可以轻松地动刀了。”
他又说：“牛的骨头关节之间是有空隙的，而我的刀非常锋利。我用这把薄薄的刀切进这些空隙，非常容易。所以，尽管我已经用了这把刀十九年，杀了几千头牛，但它还是像新的一样，一点都没有坏。”
这个故事后来变成了一个成语——游刃有余。
它告诉我们，只要我们做事顺其自然，就可以做得很好，不会感到紧张或困难。
Long, long ago, there was a king named King Liang Hui.
He had a cook who was very good at cooking. Everyone called him Cook Dao.
One day, Cook Dao was going to kill a cow for King Liang Hui.
He gently touched the blade with his fingers and leaned his knee on the cow's body.
With a 'click', the hide and bones separated!
King Liang Hui saw this and was very surprised. He asked Cook Dao, "How did you do that?"
Cook Dao smiled and said, "Because I already understand the principle of using a knife."
Cook Dao continued, "When I first started learning to slaughter cows, I saw the whole cow and didn't know where to start. But after three years of study, I began to see only the tendons and bones of the cow. Now, I don't need to look to feel the bone structure of the cow. I can easily move my knife."
He also said, "There are gaps between the bone joints of the cow, and my knife is very sharp. I use this thin knife to cut into these gaps, which is very easy. So even though I have been using this knife for nineteen years and killed thousands of cows, it is still as new as ever and has not broken at all."
This story later became an idiom - Adept at Cutting.
It tells us that as long as we follow nature in what we do, we can do it well without feeling nervous or difficult.
