In the history of china for thousands of years in ancient times, the dream of every emperor is to complete the great unification, Qin Shi Huang was the first person to complete the unification, but at the end of the Qin began to split, Liu Bang completed the great unification and after several generations of emperors' hard work, the Han Dynasty developed unprecedentedly strong, at the end of the Eastern Han Dynasty the country split again, until the Western Jin Dynasty was reunified.
Even if the ethnic minorities occupy the Central Plains, they will accept this tradition of our country since ancient times and complete the unification of the country, the Yuan Dynasty even extended its territory to Europe, the Qing Dynasty also completed the unification of the country, and there is a problem in the unification of the country is orthodoxy, in ancient times only with orthodox titles can occupy the great righteousness. In the Eastern Jin Dynasty, China split into two forces, one was the Eastern Jin Dynasty and the other was the Former Qin. At that time, Former Qin had unified the north, but the Eastern Jin Dynasty settled in a place, but at that time, Former Qin was founded by the Yu people, and the Eastern Jin Dynasty belonged to the Han nationality, so according to orthodoxy, the unification of the Eastern Jin Dynasty should meet the wishes of the Han people.
383 years ago, Qin sent an army of 900,000 troops to attack the Eastern Jin Dynasty, and in desperation, the Eastern Jin Dynasty could only meet the battle, but there were only 80,000 soldiers, and 900,000 to 80,000 was absolutely crushed. Therefore, at that time, the emperor of Former Qin sent Zhu Xu to the Eastern Jin Dynasty to persuade him to surrender. However, Zhu Xu believed that the Eastern Jin Dynasty was the orthodox, so after he came to the Eastern Jin camp, he not only did not persuade him to surrender, but also paid a lot of attention. After hearing Zhu Xu's attention, Xie Xuan, the commander at the time, gave Jian Jian a letter saying: Although our army is weak and small, we don't want to tie our hands and capture it, you let the troops take a few steps back, and when my men and horses cross the river, we will fight again.
Without hesitation, Jian Jian, who thought he had the right to win, agreed to Xie Xuan's request and ordered the troops to retreat, and just as the great battle was about to begin, the troops suddenly retreated, which made the soldiers of Former Qin panic a little. At this time, Zhu Xu suddenly shouted: The Qin army has been defeated! Suddenly frightened that the Qin army collapsed into an army, and the main general Gong Rong even tried to stop it, he could not do anything, and was finally killed by the Jin army that chased after him, and the Qin army that lost the commander was even more headless and fled for his life, this battle was a big defeat, 900,000 troops fled with dead and wounded, only 100,000 were left, and they were also injured, and this time they were defeated.
