男人不懂姨妈得痛女人不懂大JB得重
[nán rén bù dŏng yí mā dé tòng nǚ rén bù dŏng dà jb dé zhòng]
In an exaggerated manner, this implies that there is a mutual misunderstanding between men and women. For instance, men don’t understand the pain women endure during menstruation, while women may not fully comprehend other male-specific issues.
