人痞心干净
[rén pĭ xīn gān jìng]
This name combines a seeming contradiction. 'Pí' can refer to being naughty or rogue-like, and here expresses someone who might appear rascally (rascal, in many contexts can imply being mischievous but not evil) or unconventional in character; while 'heart is clean' indicates having an innocence or honesty within one's core. A person who may seem naughty on the outside, yet inside has a pure heart.
