Abstract: After the Manchus came to rule the Central Plain, the Qing court took measures to establish the secondary capital, Shengjing. The establishment of the secondary capital reflected the ruler’s political objective of “adopting Han legal institutions”, and the economic policy of “recruiting people to reclaim wasteland”. It also included the practices of “eastern inspection tours” to worship ancestors, the remodeling of the secondary capital, and the “prohibition of immigration” to this area. Although the Qing rulers regarded Shengjing as a “fundamental region” of Manchuria and they tried their utmost to strengthen and stress Manchuria identity, but after the migration of large numbers of Han Chinese and the intensification of the dependency between Han people and bannermen, the Shengjing region became a pioneering area for agricultural civilization. The area inevitably became the foundation for a fusion of the traditional Han farming culture of China Proper and the Manchurian “fishing and hunting” civilization or “inner Asian factors”.
