Agree on most part. what i want to say is , it's still too complex to excluse all the situation,though. two people maybe like each other and willing to get married, but they can't for some reason - financial(getting married takes money) or whatever it takes incase they seperate some day,then, living together seems to be a solution. i am not saying this is right, it is bad and unfair, espcially for females, simply women can't wait for long as men. It 's just what's happened in western countries.
funny to see how fast chineses try to follow western' culture' before they got whole idea of what it is like, and do whatever. bad excuse, it's shame.
