Abstract: I have been curious about the documented rules that the Manchu conquerors forced Han Chinese officials and merchants in the inner city of the capital to move out in the early Qing dynasty. It seems almost impossible and too risky under the given situation that the Qing rulers would drive out a population about 6 to 7 hundred thousand in a limited period. However the historical documents indicate this rule had been severely carried out，forming the residential pattern of the Qing Peking: a Manchurian inner city attached with an outer city of Han officials and merchants. But a closer research into history of it also suggests that this segregation rule did not last very long. The article will demonstrate how the Han officials and merchants returned to the inner city afterward and when a mixing residential pattern was formed. It also unravels materials suggesting that the Manchu residents in the inner city constantly moved outside in the same period．
