男大当婚，女大当嫁，时代不同，伦理道德观念不同，人们的婚嫁观也不尽相同。汉代封建文明虽已发展到一个较高的水平，但婚嫁风俗上，原始社会古风犹存，而且封建纲常名教在两汉时期尚未形成系统周密的理论，贞节观念也未深入人心。所以汉代婚姻环境相对宽松，婚嫁观具有一定的传统性和开放性。女子择夫尚富贵和才能，不重贞操，不重尊卑名分；男子择妇尚相貌，也尚财富，对于女子贞节并不看重。此外，本文还运用相关史料，分析了汉代婚外关系的广泛存在。 When men are married, women are married, times are different, ethics are different, and people’s marriages are not the same.

In addition, this article also uses the relevant historical data to analyze the widespread existence of extramarital relations in the Han Dynasty.
