爷们讲讲义气保护媳妇娘们讲讲原则亲亲相公
[yé men jiăng jiăng yì qì băo hù xí fù niáng men jiăng jiăng yuán zé qīn qīn xiāng gōng]
It translates loosely as 'Men should show loyalty protecting wives, while women should uphold their principles when dealing with their own husbands'; highlighting gendered expectations on relationship roles with hints on cultural value judgments.
