The Ming army was relatively strong, and they brought unprecedented pressure to the Ming Dynasty. The most powerful cavalry in the late Ming Dynasty was Jurchen. It is said that the Eight Banners cavalry are very good at riding and archery. We can see that when the Eight Banners fought Mongolia under the leadership of Huang Taiji, the Mongols were also a people riding horses, and their folk customs were also very strong. However, Huang Taiji only sent more than 20,000 cavalry and defeated more than 400,000 people in Mongolia.

At that time, in the Battle of Lake Sal, the Ming Army and the Eight Banners Army fought for the first time. At that time, the Ming army advocated that jurchen must be destroyed. Emperor Wanli also issued an imperial edict, ordering its destruction within a certain period of time. At that time, the Ming army was equipped with guns, which played a great role in the Korean War of Resistance against Japanese Aggression, but these guns had short range and slow loading speed. They are no match for cavalry in speed and range, and the archery of the Eight Banners is more deadly than guns.

At that time, the Ming army was an elite, with nearly 100000 people. At that time, the allies of the Ming Dynasty, Hercynian Nuzhen, Mongolia and North Korea, sent 1 10000 people against the Ming army. The troops rushed back to Kim's lair. Later, when attacking the Zhejiang soldiers, the strong wind blew to the Ming army in time, and the golden cavalry went with the wind, and the arrow became stronger. Qi Jiguang's elite soldiers were all destroyed in this war, and the Korean army surrendered directly.

And the fourth Li, hearing the news, directly withdrew from the battle. Fortunately, Li withdrew from the battle, otherwise the losses of the Ming army would be even greater. In the battle of Salhu, the Ming army was still very strong, and the later the Ming army became more difficult. The battle of Salhu failed, and the field battle of Ming army ended.
