有妇之夫好男人有夫之妇好女人
[yŏu fù zhī fū hăo nán rén yŏu fū zhī fù hăo nǚ rén]
A seemingly paradoxical view on fidelity, stating 'A committed husband is a good man; a devoted wife is a respectable woman', implying that marriage brings about positive qualities in both genders by encouraging steadfastness and loyalty.
