maximum impact, so as to minimize ethnic Manchu losses. 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. The first seven years of the young Shunzhi Emperor's reign were dominated by Dorgon's regency. Because of his own political insecurity, Dorgon followed Hong Taiji's example by ruling in the name of the emperor at the expense of rival Manchu princes, many of whom he demoted or imprisoned under one pretext or another. Dorgon's precedents and example cast a long shadow. First, the Manchus had entered "South of the Wall" because Dorgon had responded decisively to Wu Sangui's appeal, then, instead of sacking Beijing as the rebels had done, Dorgon insisted, over the protests of other Manchu princes, on making it the dynastic capital and reappointing most Ming officials. No major Chinese dynasty had directly taken over its immediate predecessor's capital, but keeping the Ming capital and bureaucracy intact helped quickly stabilize the regime and sped up the conquest of the rest of the country. Dorgon then drastically reduced the influence of the eunuchs, a major force in the Ming bureaucracy, and directed Manchu women not to bind their feet in the Chinese style. However, not all of Dorgon's policies were equally popular or as easy to implement. The controversial July 1645 edict (the "haircutting order") forced adult Han Chinese men to shave the front of their heads and comb the remaining hair into the queue hairstyle which was worn by Manchu men, on pain of death. The popular description of the order was: "To keep the hair, you lose the head; To keep your head, you cut the hair." To the Manchus, this policy was a test of loyalty and an aid in distinguishing friend from foe.
