女人不能宠越宠越有种男人不能惯越惯越完蛋
[nǚ rén bù néng chŏng yuè chŏng yuè yŏu zhŏng nán rén bù néng guàn yuè guàn yuè wán dàn]
Translating to 'Don’t pamper women, the more you do, the more rebellious they become; don’t indulge men, the more you do, the worse it gets.' It conveys a cynical perspective on relationships.
