In the 39th year of the Duke of Qin (621 BC), Duke Mu of Qin died, and the crown prince Yan took the throne as the Duke of Qin Kang.
In the year of Qin Kang (620 BC), Zhao Dun, the secretary of the Jin dynasty, advocated deposing the crown prince Yigao, making Gongzi Yong the younger brother of the Duke of Jin Xiang the prince, and sending people to the Qin state to welcome Gongzi Yong back, so Qin Kang sent troops to escort Gongzi Yong back to the Jin state. However, under the pressure of Mu Wei, the Duke of Jinxiang, Zhao Dun changed his mind and replaced the crown prince Yigao with the throne as the Duke of Jinling. The Qin escort army was intercepted and ambushed by the Jin army at Linghu (令狐; southwest of present-day Linyi County, Shanxi Province), and the Qin army was greatly defeated, and Xianyi he was forced to flee to the Qin state, known in history as the "Battle of Linghu".
In the second year of the Duke of Qin Kang (619 BC), the Duke of Qin Kang sent troops to attack the State of Jin and seize the City of Wucheng in the State of Jin in order to avenge the Battle of the Fox.
In the fourth year of the Duke Kang of Qin (617 BC), the State of Jin attacked the State of Qin and captured the Shaoliang of the State of Qin.
In the sixth year of the Reign of Qin Kang (615 BC), the Duke of Qin Kang sent troops to attack the State of Jin and capture the Jin State's Qima (present-day Yongjinan, Shanxi). The Jin state sent troops to the rescue, and the two armies engaged in battle at Hequ (河曲, in modern Ruicheng, Shanxi), and the Qin army defeated the Jin army. The Jin people were worried that the shihui would cause disasters to the Jin state in the Qin state, so they sent Wei Shouyu to falsely claim to betray the Jin and surrender to Qin, and used deception to make the shihui return to the Jin state.
In the twelfth year of the Duke of Qin Kang (609 BC), Duke Kang of Qin died and his son Crown Prince Dao took the throne.
During the Qin Mugong period, there were countless military generals, who opened up territory and expanded more than a thousand miles, and once reached Hangu Pass. However, since Mu Gong's death, the giant ship of qin development has come to a brake. It was not until several generations later, when qin xiaogong was born, that the qin state began to rise again, why is this?
After Qin Mugong, when the Qin State was at its worst, it even lost the vast eastern region, and the Qin State had several times a crisis of annihilation, why was this?
Objectively speaking, on the way eastward for the Qin state, there was originally a powerful Jin state. This Jin state inherited the combat effectiveness of the Zhou royal family, and several generations of kings worked hard to govern, becoming the biggest obstacle to the Qin state's eastward advance into the Central Plains. Even if the three families were divided into Jin later, but there was a State of Wei to inherit the military strength of the State of Jin, and there were famous generals such as Wu Qi, the future of the State of Qin was therefore unclear. In fact, these may all originate from the Qin Mugong, that is, the Qin Kanggong.
The successor of Duke Mu of Qin was not a good monarch. When Qin Kanggong was young, he had also seen the big formation, and there were several influential people at that time, including Jin Wengong. During the Qin Mugong period, the Qin state fought with the Jin state several times, which can be said to be more defeated than victorious, and Qin Kanggong should have a deep understanding.
Qin Kanggong, this person, attaches great importance to the central plains figures, when sending jin Wengong back to jinguo, he and Jin Wengong felt sorry for each other, and also gave poems to commemorate, which shows that this person still has the art of knowing people and knows how to be with excellent talents. In the Book of Poetry, there is: "I sent my uncle to Weiyang, why give it to him, and the road car took yellow." I send my uncle, and I think about it. Why give it away, Qiong Zhen Jade Pendant. "How Jin Wengong really viewed Qin Kanggong is not mentioned in the history books. But it can be mentioned that Jin Wengong was definitely not sincere with this nephew. The strength of the Jin state is doomed to the hegemony of the Qin state.
Qin Kanggong's admiration for the characters of the Central Plains began with the Duke Wen of Jin and later the Jin Dynasty's courtiers. The state politics of the Qin state basically evolved from the culture of the Central Plains to the culture of the State of Jin, that is, the State of Qin began to become the apprentice of the State of Jin from this time, and also tended to follow the State of Jin. Duke Qin Kang was deeply poisoned by the Zhou culture and etiquette, and his rigid observance of some so-called etiquette in the Central Plains was regarded as a good monarch among the princes and nobles, and it was foolish to look at it during the years of war and chaos. For example, since the death of Duke Wen of Jin, diplomatic relations with the State of Qin have been torn apart.
Duke Kang of Qin was naturally dissatisfied with the ungratefulness of the Jin state and also launched an army to go to war with the Jin state. The key problem is that the person used by Qin Kanggong at this time is the important courtiers of the Jin State, and this person's identity, in the eyes of the history books, is more like a spy-like figure, who is reused by Qin Kanggong, on the battlefield, but eventually returns to the Jin Kingdom. Interestingly, Qin Kanggong was fooled by the courtiers of the Jin Dynasty, and actually sent all the family members and relatives of the General Association back, and the war with the Jin Dynasty can be said to be a self-retreat without a fight, which can be described as stealing chickens and not corrupting rice.
