然并卵 (ran bing luan) is a popular internet term that rose to fame in 2015 and is an abbreviation of "然而并没有什么卵用".
The meaning of this expression is to show that while some things may seem very complicated or high-end, they are in fact not and has no substantial effect or does not achieve the results as ideally envisioned. It is also frequently used to express a sense of helplessness and ridicule.
An exmaple would be "XXX其实是一个然并卵的游戏啊!"
(xxx qíshí shì yīgè rán bìng luǎn de yóuxì a!)
which translates to : "XXX is actually a game without much substance!"
