Geng Zhongming
This multi-ethnic force conquered China for the Qing, The three Liaodong Han Bannermen officers who played key roles in the conquest of southern China were Shang Kexi, Geng Zhongming, and Kong Youde, who governed southern China autonomously as viceroys for the Qing after the conquest. Han Chinese Bannermen made up the majority of governors in the early Qing, stabilizing Qing rule. To promote ethnic harmony, a 1648 decree allowed Han Chinese civilian 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 with the permission of their banner company captain if they were unregistered commoners. Later in the dynasty the policies allowing intermarriage were done away with.
