The Yi keyin is more compact than t

The Yi keyin is more compact than the Beijing style of residences which are noted for their regal air and aristocratic grandeur. The buildings on all four sides are two-storied and connected. This configuration facilitates ventilation and exposes the rooms to less direct sunlight, which suits the local warm climate. The walls are high and with few windows so as to prevent the wind and the sand. There are three principal rooms with two wing-rooms on either side.
