曾小贤都比你纯洁一百倍
[céng xiăo xián dōu bĭ nĭ chún jié yī băi bèi]
In this Chinese internet jargon, Zeng Xiaoxian is a reference to a character from the show 'Love公寓'. This nickname sarcastically compares someone's impurity or naughtiness by saying they're less pure than Zeng Xiaoxian who may still have issues of his own.
