it depends. usually some couples will still live with the husband's parents after marriage. and the bad relationship between the daughter-in-law and mother-in-law are always mentioned of course there are many exceptions.
the most important things for a family is harmony so if you enjoying the atmosphere in a big family that wii benefit you a lot.. if you dont, youcan choose to move out.. one thing i think we haveto keep in mind is that we must take care of our parents no matter where we choose to live..
I think a little distance would be quite nice for both of married couple and their parents. parents should let go of their children, let them have space to cultivate their own marriage life. life style between old generation and younger generation have a wide gap. bridging the gap is not always easy thing to do. so, its so much easier to live each other's life separately. but, don't forget that the filial duty is can't be ignored, even if you are living away from your parents.
