Long long ago, several people had a jar of wine among them and all of them wanted to drink it by himself. So they set a rule that every one would draw a snake on the ground and the man who finished first would have the wine. One man finished his snake very soon and he was about to drink the wine when he saw the others were still busy drawing, so he decided to draw the feet to the snake. However, before he could finish the feet, another man finished and grabbed the jar from him, saying, "Who has ever seen a snake with feet?" The story of "Draw a snake and add feet to It." tells us going too far is as bad as not going far enough.

古時幾個人分一壺酒。他們都想獨自喝完那壺酒，所以就定了一個規(guī)矩：每人在地上畫一條蛇，誰畫得最快，這壺酒就歸誰。有一個人很快就把蛇畫好了。他正打算喝這壺酒時，看見別人都還在忙著畫，就決定給蛇再畫上幾只腳。結果，他的蛇腳還沒加完，另一個人已經(jīng)把蛇畫好了。那人一下把酒壺奪了過去，說："有誰見過長腳的蛇?"。這個故事告訴我們這樣的道理：做得過分和做得不夠都是不對的。
