彩色世界少了黑白
[căi sè shì jiè shăo le hēi bái]
The meaning of this nickname is that 'In the colorful world, the black and white are missing.' In general, colorful things represent rich emotions, desires and changes. On the contrary, the black and white part often refers to pure, monotonous but true essence, which suggests a reflection on how materiality may lead people to ignore what truly matters in life.
