Returnees can't get married, probably because, on the one hand, girls who can study abroad have relatively rich families, so their satisfaction is very weak, and you need to be very attentive to them to be satisfied. On the one hand, they have seen the world and are more open abroad, so they may have a better understanding of their feelings. On the other hand, people who can study abroad are relatively independent and have a weak sense of dependence on the opposite sex. If they are in love and boys are not needed, their feelings can easily spread to other soils. Therefore, returnees cannot marry.
