During the interviews, we found out that the layout called 'ruler turn' is typically adopted in modern dwelling, in another word, the whole dwelling looks like a square.
At the vertex of the right angle is the kitchen, a place for cooking and dining. At the long straight line are the two bedrooms, and between them is the lobby room, which is a place for sacrifice. At the short straight line are one or two bedrooms. Generally, there's no space for food storage in modern dwelling, so food was put in those bedrooms instead. Behind the bedrooms are several low rooms for raising pigs and cows. And every household has a yard for drying corps.
