What do you mean by closing the room?

The house with the master bedroom and the back bedroom facing the sun is called Sanyang House. There is no dark side, and the main building usually faces south.

The wing house is the house next to this building, usually in the first and last unit of this building. Because one side of this house is the outer wall of the building, the temperature of this house is generally lower than that of other houses in winter. Commonly known as mountain houses, such as buildings facing south, the easternmost and westernmost houses are called wing houses.
