Qingning Palace is five bays wide, but its entrance does not occupy the middle bay. The door opens toward the eastern end. This small asymmetry changes how the building works: much of the interior extends away from the entrance as a connected space, rather than separating neatly into rooms on either side of a central hall.
The palace museum calls the arrangement a pocket house. The image describes a plan with an opening near one end and a larger interior beyond. Built for Hong Taiji, the ruler who proclaimed the Qing dynasty in 1636, Qingning was both a royal home and a setting for household rites. Its comparatively restrained exterior cannot explain those functions on its own. The door begins that explanation.
