In his Dazhuangshi biji, Liu Dunzhen identifies the continuity of the spatial pattern of “front main hall with rear bedroom” (qiantang houshi) as a key criterion for and clue to Chinese architectural history. This continuity is significant for the study of architectural transformation stimulated by etiquette, social customs, and rituals. Based on historical documents and recent archaeological excavations, the paper explores the diversification and division of hall and room spaces/ functions during the period of the Six Dynasties. Although the new composition of “front and rear palatial halls with less eminent halls on both sides” (qianhou dian, dongxi tang) emerged at that time, the traditional pattern still continued to have appeal for ritual spaces, for example the front hall in the palace or in the houses of scholar-officials.
