Taking Weipo village (Laojie) near Luoyang, as part of research works exploring how to conserve the traditional houses, in this paper we focus on the changes of uses and their physical influences on the houses. We make clear the detailed process the extended families have become nuclear, the ownerships have been divided and what changes have been added to the original houses. And we find that the traditional order not only have been lost, but the changes also resulted in deterioration of living conditions, moving to new houses, and decline of the center of Laojie nowadays.
