Why is it rumored that "if you don't take a Daiwai girl, you won't marry a Dongzai man"?

Students rumored that there are a lot of girls in the university, many of whom have money and many of whom do not have money, and many of whom are of high quality and many of whom are of low quality. One part, no money, low quality, due to the nature of the girl climbing, a kind of out of the reason I do not understand, and outside the rich boss together, do escort, escort chat, and even do up ernai, anyway, is the big outside of some women's style is not good. Some of them are like this, but most of the social ones are from Daiwai.

The men of Dongcai are very few, and all day long and the women soak together, some feminization, become particularly effeminate, and then there is their proximity to the water table first, a lot of and sister soak together.
