During the Manchu period, the Manchu people were also oppressed by the Manchu nobles. At that time, the aristocratic class of Manchu society controlled politics, economy, culture and other aspects to discriminate and oppress the lower class of Manchu people, making the life of the lower class of Manchu people very difficult. At the same time, many Manchu people participated in the Anti-Qing and Revival Movement. The Anti-Qing and Revival Movement was a political movement by some people who missed the Ming Dynasty to oppose the rule of the Qing Dynasty. In these movements, the Manchu people played an important role, including some famous leaders such as Zhang Xianzhong's adopted son Dong Biyou and Li Dingguo's student Liu Zongzhou. In addition, the Manchurian army also played an important role in the three wars. The Three Wars referred to a series of wars between the Ming and Qing dynasties in the late Qing Dynasty, which eventually led to the Qing Dynasty's victory. The Manchurian army performed well in the war, defeating the Ming Dynasty army and contributing to the unification of China.
