画蛇添足
huà shé tiān zú
to ruin something by adding unnecessary details
A good thing becomes worse when you keep adding what it does not need.
Story background
In an old story, several people competed to finish drawing a snake first so they could win a pot of wine. One person finished early, then proudly added feet to the snake. Before he was done, another person finished a normal snake and claimed the prize. The lesson is simple: once something is already complete, extra decoration can destroy it.
古时候几个人比赛画蛇,谁先画完谁就能得到一壶酒。有一个人很快画完了,却自作聪明地给蛇添上了脚。结果在他画脚的时候,别人完成了正常的蛇,拿走了酒。这个故事提醒我们:事情已经够好了,再多加反而可能毁掉它。
Example in context
这个方案已经很清楚了,再加那么多功能有点画蛇添足。
Zhège fāng'àn yǐjīng hěn qīngchu le, zài jiā nàme duō gōngnéng yǒudiǎn huà shé tiān zú.
The plan is already clear. Adding that many extra features feels unnecessary and may ruin it.
Usage tip
Use it when someone over-designs, over-explains, or keeps polishing something that was already finished.
常用来形容过度设计、过度解释,或者一件事明明已经完成却还要多加东西。
How to remember it
Remember the image first, then the moral or emotional tone behind it.
Repeat the example sentence aloud before trying to invent your own variation.
Use one idiom at a time in real conversation so it sounds natural instead of theatrical.
