Due to their history as defectors that helped to topple the Southern Ming dynasty, the Three Feudatories failed to win over the support of the general Han populace and were eventually defeated by the Qing forces.
For instance, the navy of Geng Zhongming and Shang Kexi brought about the quick capitulation of Joseon in 1636, allowing rapid advance into Ming territories without worrying about what was behind.
In Yunnan and Guizhou, Wu Sangui was granted permission by the Shunzhi Emperor to appoint and promote his own personal group of officials, as well as the privilege of choosing warhorses first before the Qing armies.
Wu Sangui's forces took up several million taels of silver in military pay, taking up a third of the Qing government's revenue from taxes.
In Fujian province, Geng Zhongming ruled as a tyrant over his fief, allowing his subordinates to extort food supplies and money from the common people.
Kangxi went against the views of the majority in the council and accepted the three lords' requests for retirement, ordering them to leave their respective fiefs and resettle in Manchuria.
In 1674 both Geng Jingzhong in Fujian and after Shang Zhixin, the man who massacred Guangzhou, died, his son followed suit in Guangdong.
Zheng Jing, ruler of the Kingdom of Tungning, led an army from Taiwan and landed in Fujian and Guangdong to fight and join the rebel forces.
[12] Manchu Generals and Bannermen were put to shame by the performance of the Han Chinese Green Standard Army, who fought better than them against the rebels.
In 1678, Wu finally proclaimed himself emperor of the Great Zhou Dynasty (大周)[22] in Hengzhou (衡州; present-day Hengyang, Hunan province) and established his own imperial court.
Sichuan and southern Shaanxi were retaken by the Han Chinese Green Standard Army under Wang Jinbao and Zhao Liangdong in 1680,[24] with Manchu forces involved only in dealing with logistics and provisions, not combat.
In 1681, the Qing general Zhao Liangdong proposed a three-pronged attack on Yunnan, with imperial armies from Hunan, Guangxi and Sichuan.
Cai Yurong, Viceroy of Yun-Gui, led the attack on the rebels together with Zhang Tai and Laita Giyesu, conquering Mount Wuhua and besieging Kunming.
[33] In 1685, the Qing used former Ming loyalist Han Chinese naval specialists who had served under the Zheng family in Taiwan in the siege of Albazin.
[21][34] Former Ming loyalist Han Chinese troops who had served under Zheng Chenggong and who specialized at fighting with rattan shields and swords (Tengpaiying) 藤牌营 were recommended to the Kangxi Emperor to reinforce Albazin against the Russians.
Kangxi was impressed by a demonstration of their techniques and ordered 500 of them to defend Albazin, under Ho Yu, a former Koxinga follower, and Lin Hsing-chu, a former General of Wu Sangui.
[35][36][37] "[the Russian reinforcements were coming down to the fort on the river] Thereupon he [Marquis Lin] ordered all our marines to take off their clothes and jump into the water.
