男人大可不必百口莫辩女人大可不必骚首弄姿
[nán rén dà kĕ bù bì băi kŏu mò biàn nǚ rén dà kĕ bù bì sāo shŏu nòng zī]
This saying means 'Men don't need to overly defend themselves, and women don’t need to flirt around pointlessly', emphasizing authenticity and not needing to perform for others’ approval in terms of gender roles and interactions.
