Chinese from eastern Liaodong who joined the Eight Banners were known as "tai nikan", the Han who defected to the Qing at Fushun were known as Fushan Nikan and were considered part of the Tai Nikan. The Tai Nikan were distinguished from the later Han Chinese who joined the banners between 1629-1643 and originated from western Liaodong, Shanxi, Shandong, and Zhili, and were known as "fu xi baitangga". Both groups were part of the Chinese Banners before the Qing crossed over Shanhai pass in 1644, and as such were both distinguished from Han who were incorporated into the Chinese Banners after 1644 when the Qing ruled China. The pre-1644 Chinese Bannermen were known as "old men" 旧人 . A mass transfer into the Manchu banners of every single Fushun Nikan, and specifically chosen tai nikan, Koreans, and Mongols was enacted by the Qianlong Emperor in 1740. Manchu Bannermen in Beijing were driven into poverty just decades after the conquest, living in slums and falling into debt, with signs of their plight appearing as soon as 1655. They were driven to the point where they had to sell their property to Han Chinese, in violation of the law. Originally in the early Qing the Qing emperors both took some Han Chinese as concubines and a 1648 decree from Shunzhi allowed Han Chinese men to marry Manchu women from the Banners with the permission of the Board of Revenue if they were registered daughters of officials or commoners or the permission of their banner company captain if they were unregistered commoners, it was only later in the dynasty that these policies were done away with and the Qing enacted new policies in their xiunu system of drafting Banner girls for the Imperial Harem by excluding daughters of Han commoners. Chinese Bannermen (Hanjun, or Han Bannermen) frequently married Han civilian women and this was permitted by the Qing emperors, however the Qing emperors were distressed to find girls in the Banners as a result of these intermarriages following Han civilian customs in clothing and jewelry when they ended up being drafted for palace service. The Qing formulated policies to remove and shut out daughters of common Chinese Bannermen (Hanjun, or Han Bannermen) from serving in the Imperial palace as maids and consorts, exempting them from the draft, asserting that it was doing it out of concern due to the economic plight of Chinese
