The Qing showed in propaganda targeted towards the Ming military that the Manchus valued military skills to get them to defect to the Qing, since the Ming civilian political system discriminated against the military. The three Liaodong Han Bannermen officers who played a massive role in the conquest of southern China from the Ming were Shang Kexi, Geng Zhongming, and Kong Youde and they governed southern China autonomously as viceroys for the Qing after their conquests. Normally the Manchu Bannermen acted as reserve forces while the Qing foremost used defected Han Chinese troops to fight as the vanguard during their conquest of China.
