鱼目混珠

鱼目混珠

从前，在街市上，住着一个名叫满意的人。有一次，他买到一颗径长一寸的闻所未闻的大珍珠。特别喜欢就藏了起来。满意有个邻居名叫寿量，他在路上发现一颗很大的鱼眼睛，便误以为是珍珠就捡回家收藏。事有凑巧，不久两人都得了一种奇怪的病，卧床不起。一日街上走来一个游方郎中，诊断后说他们两人都需要用珍珠的粉末和药材才能治好。他们都把自己的珍珠拿出来让郎中看，满意打开盒子，郎中叹道：“果然是罕见珍宝！”，但是看到寿量的“珍珠”时，大笑着说：“这哪是什么珍珠，这是海洋中一种大鱼的眼睛。真是鱼目混珠，这哪能治好你的病啊！”

鱼目混珠比喻以假乱真，以次充好。

Passing Off Fish Eyes as Pearls

In the Han Dynasty (hàn cháo 汉朝), there was a Taoist called Wei Boyang who wrote a book on the making of pills of immortality. In this book there is the following line:” Fish eyes can’t be passed off as pearls, and bitter flea-bane can’t pretend to be tea.” Fish eyes look like pears, but are valueless.

This idiom is used to mean passing off the sham as the genuine.
