Why the millions of troops of the former Qin Dynasty could not defeat the 100,000 troops of the Eastern Jin Dynasty

The former Qin and the Eastern Jin were both famous political powers in Chinese history. The battle between them was also one of the famous battles in history. However, there were many reasons why the former Qin army could not defeat the Eastern Jin army. The political backgrounds of the former Qin Dynasty and the Eastern Jin Dynasty were different. The former Qin Dynasty was the afterglow of the Qin State, and the founder was the Zhao family with the surname Ying. The Eastern Jin Dynasty was a political power passed down from generation to generation by the Wang family. During the Eastern Jin Dynasty, the Wang family had extremely high power and influence. The differences in the cultural backgrounds and values of the two governments led to differences in the morale and tactics of the army. The geographical locations of the former Qin Dynasty and the Eastern Jin Dynasty were also different. The former Qin Dynasty was located in the north of China, and the Eastern Jin Dynasty was located in the middle of China. The geographical location of these two political powers had an important impact on the victory of the war. The former Qin Dynasty was located in the frontier fortress, while the Eastern Jin Dynasty was located in the Jiangnan area, which was relatively flat. The former Qin could use its terrain advantage to restrict the movements of the Eastern Jin army, while the Eastern Jin could use its terrain advantage to counterattack. The former Qin and the Eastern Jin had different armies. The army of the former Qin Dynasty was mainly composed of Xianbei people while the army of the Eastern Jin Dynasty was mainly composed of Han people. The cultural and religious differences between the two ethnic groups would also affect the combat effectiveness of the army. In addition, the military equipment and training of the former Qin and Eastern Jin armies were also different. For all these reasons, the former Qin army could not defeat the Eastern Jin army. Although the former Qin Dynasty had a million troops, there were internal divisions and contradictions. The morale of the army was not high and the tactics were single. The Eastern Jin Dynasty had a hundred thousand troops, but there were also internal contradictions and contradictions. The high morale of the army and the rich tactics led to the failure of the former Qin Dynasty.
