Li Chengdong was born in the late Ming and early Qing Dynasties, which is also an era of frequent wars. When Li Chengdong grew up, he took part in the peasant uprising, fought against the Qing army with others and supported the Ming Dynasty. Unfortunately, in the process of many defections, anti-Qing and regaining sight, he fell into a puddle because of resisting the enemy's pursuit. However, the Ming Dynasty was a spent force, unable to resist the menacing Qing army. Even though some people shouted slogans, they still lost to the Qing army. Later, during the uprising, Li Chengdong surrendered to the Qing army. Become a member of the Qing army.

After surrendering to the Qing army, Li Chengdong truly reflected his political stance and made certain contributions to the Qing army. But the tactics are too cruel. He once led the Qing army to slaughter the residents of a city. Burning and looting in the city, doing evil. No different from bandits, no brotherhood at all. Another great contribution was that Li Chengdong killed two Ming emperors after surrendering to the Qing army, which was a great military achievement. This was a great move at that time. After you calm down, you will get a generous reward.

However, things have turned into raising. Li Chengdong was not satisfied with the reward of the Qing court, and thought that his meritorious service should be much higher than his current official position, but the result was quite different from his own idea. So, in a rage, Li Chengdong defected again, turned to surrender to the Ming army and became a member of the Ming army again. His life is extremely repetitive. Although he chose anti-Qing because of insufficient reward, this statement is too one-sided. You know, after he surrendered to the Qing court, he would be discriminated against by some Manchu officials with orthodox blood because of his race. On the other hand, as a former Ming people, it will naturally be touched in the process of repression. For various reasons, Li Chengdong once again became a loyal member of the Ming Dynasty.

Finally, he died in the confrontation with the Qing army. Although it was a confrontation, he did not die on the battlefield, but was drowned. History is so dramatic that after his death, Ming Chengzu called him a "brave man".
