疯子的生活很安静
[fēng zi de shēng huó hĕn ān jìng]
The irony conveyed here is striking - mad people tend to be associated with erratic actions or chaotic lives whereas this person uses 'quiet' to subvert expectations. By combining opposites in the sense that the life of the so-called 'crazy person' is actually peaceful, the net user perhaps wishes to express that even seemingly turbulent or unconventional lifestyles can also have quiet depths within them. In short, it expresses a paradox where one leads a wild yet inwardly calm lifestyle, indicating an introverted, possibly creative personality.
