Liaodong fighters, a cavalry of Li and Li Jianli, the company commanders of Liaodong in the Ming Dynasty, were mainly composed of Li's servants and servants, with about 3,000 people. They are well equipped and good at surprise and conquest. This unit was not in the financial system of the Ming Dynasty, nor was it an official unit of the Ming Dynasty. They only obey the command of Li and his descendants.

This unit played an important role in the Mongolian War and the Korean-Japanese War in Wan Li. Nurhachi, Emperor Mao of the Qing Dynasty, was once a slave of the Li family and vowed to be loyal to Li for life. After Li's death, the railway station was finally submerged in history, because there was no good general to unify the soldiers.

Ning Guan Tieqi was a cavalry unit with strong fighting capacity actively formed by Yuan Chonghuan and Zu Dashou in the late Ming Dynasty. The number is small, but it is the most elite army of Daming. What needs to be emphasized here is that the main members of Ning Guan Tieqi in the later period were Liao people, most of whom were victims of Nurhachi rebellion. They like to ride horses and shoot arrows, and they have great hatred for Houjin. This unit actively resisted the intrusion of the late Jin Dynasty from Ningyuan, Shanhaiguan and Jinzhou. Wu Sangui, the last company commander, selected fighters and trained 5,000 elite fighters, which made the late Jin Dynasty fearful.

As far as combat effectiveness is concerned, Liaodong fighters are invincible in the hands of Li and Li, and no one dares to confront them. They are the most powerful fighters in Northeast Asia. Only later, after Li's death, Li Jiajun, as a private armed force, gradually withdrew from the historical stage. On the other hand, Ning Guan soldiers are different. In the battle with the late Jin, they fought and lost many times, which made Nurhachi and Huang Taiji feel the bravery of Ning Guan soldiers.

Ning Guan fighters, in the first world war of Ningyuan, directly knocked down the elite of Houjin with a three-eye device, and Nurhachi was seriously injured and died. In nine thousand fighters to defend Beijing, thousands of miles to help, directly repelled Huang Taiji's attack. In the later period of following Wu Sangui, he directly resisted the threat of the late Jin Dynasty to the Ming Dynasty.

After the Qing Dynasty in Wu Sangui, Ning Guan fighters, together with the Eight Banners Army, directly wiped out 100,000 peasant troops in Li Zicheng, and then went to Beijing to drive Li Zicheng away, pursuing all the way until Dashun Army was wiped out. Later, the regime of Daxi was destroyed, and hundreds of thousands of troops from Nanming were destroyed in the south.

Under the policy of Emperor Kangxi's vassal-cutting in Qing Dynasty, Wu Sangui rose up, led a veteran of Ning Guan's imperial fighters, directly occupied more than half of China, and annihilated nearly 500,000 Qing troops. Then, disappear in the dust of history. It can be seen from here that Ning Guan soldiers are the most powerful fighters.
