In 626 BC, after the death of Jin Wengong, the second monarch of the vassal states in the Spring and Autumn Period, his son Jin Xianggong succeeded him to the throne. The corresponding state of Qin was in the period of Qin Mugong, the first prosperous king.
At first, Qin Mugong wanted to realize his dream of entering the Central Plains by supporting the monarch of the State of Jin, but since Jin Wengong, it has formed substantial resistance to the eastward development of the State of Qin. Although Jin Wengong died in 626 BC, Duke Xiang of Jin, who inherited the throne of the State of Jin, was no worse than his father Jin Wengong.
When Duke Xiang of Jin succeeded to the throne, Qin Mugong thought that he had contributed to the State of Jin, and his attitude was not very friendly, or he treated Duke Xiang of Jin as an elder, while countries such as Weiguo were not friendly. They all think that after Jin Wengong's death, the State of Jin did not become so powerful. Chu, once defeated in the battle of Chengpu, is also ready to move.
Therefore, during Duke Xiang of Jin Dynasty, he was deeply dissatisfied with Qin's attack on his own country, and launched a food war to destroy Qin Jun, and then attacked Zhai Guo, which was still very powerful, making Zhai Guo unable to recover for a long time. Finally, in the battle of Feishui, he deeply humiliated Chu's army, making Chu angry but helpless.
In 626 BC, the restless Duke Xiang of Jin attacked a country that didn't respect himself. Unexpectedly, at this time, the State of Qin attacked the State of Jin on the pretext of losing the Battle of Xue Yao. Unfortunately, the marshal captured the fighter first, withdrew from the battlefield of Wei in advance, and was defeated again.
In this way, the state of Jin under the leadership of Duke Xiang of Jin is not weaker or even worse. If we want to fight Qin with the power of dumping the country, I'm afraid Qin still can't get a good result.
At the Battle of Wang Guan, the State of Qin was furious. Personally, Meng and others served as military commanders. After crossing the Yellow River, they burned all the ships, which made Qin Jun's momentum reach its peak. And the purpose of Qin Mugong is also very clear, I just came to find my son, who let you ever bully me. Zhao's failure in the state of Jin provided Duke Xiang of Jin with a new idea: stick to the city, avoid conflict with Qin Jun, and go back by himself when he grows up.
In the end, Qin Mugong's patriotic army captured only two cities of Wang Guan in the State of Jin. After a month's walk in the state of Jin, Qin Jun went to collect the bodies of Qin Jun soldiers who died in the battle of Yaozhi, and then went home.
From then on, the state of Jin really began to adjust its thinking, treating the vassal States with courtesy and serving people with virtue, which made the state of Jin obey the vassal States throughout the Spring and Autumn Period.
The battle of Wang Guan, the State of Qin, only captured two small towns in the State of Jin, which made Qin Mugong realize the strength of the State of Jin and the weakness of the State of Qin. I also realized that if I want to dominate the Central Plains, the State of Jin is always a hurdle that I can't get around, and the State of Qin is not sure about it.
Since then, Qin Mugong has been content to expand its territory to the west and north and dominate Xirong. With the help of Jianshu, Priscilla and Meng, Qin annexed more than 20 Xirong countries to the west during the period, benefiting thousands of miles and gradually becoming stronger.
