Since the destruction of the Daluo family of Qin Wei's own family by Xi Rong, Qin Zhong, the fourth generation of Qin Wei's family lord, was killed in battle on the way to fight against Xi Rong, and Qin Wei formed a life-and-death vendetta with Xi Rong.
As the eldest son of the Duke of Qinzhuang, shi father will become the sixth generation of qin's family lord in the future. However, Shi Father shirked the crown prince's throne and said, "If Xi Rong killed my grandfather Qin Zhong, I must kill the king of Xi Rong, otherwise I would not dare to return to Qin Yi." ”
So his younger brother Ying Kai became the heir of Qin Wei.
From the Western Zhou Dynasty to the Spring and Autumn Warring States, the struggle for the throne of the crown prince often deduced the cruelty of human nature, and there were very few courtesies like the Qin State. Although the princes of the Central Plains also abdicated, the ending was not very beautiful.
The "overlord of benevolence and righteousness" Song Xianggong Zifu was the eldest son of Song Huangong, who was seriously ill at that time, and Zifu, who was supposed to take the throne, thought that his brother Muyi Renyi was righteous, so he pleaded with Song Huan to make Muyi the monarch.
After Mu Yi knew that his brother had abdicated the throne, he refused to accept the crown prince's throne and said, "Isn't this the greatest benevolence to give up the country to me?" Moreover, the abolition of the concubine is not in line with the system. In order to avoid his brother's Jean Xian, Hinmu Yi fled to Weiguo. In the end, Zifu ascended the throne as The Duke of Song Xiang.
The beauty of Song Xianggong's kingdom was deeply admired, but the descendants of Song Xianggong and the descendants of Muyi did not have the virtue of humility. After the death of Song Xianggong, the descendants of Song Xianggong and the descendants of Muyi often fought for the throne, causing chaos in the Song Dynasty and making the people miserable.
It can be seen from this that the concession of "the predecessors let the wise and the future compete for the throne" is imperfect or even unsuccessful.
On the other hand, the State of Qin did not cause civil strife because of the brothers' modesty to the throne, but a harmonious situation in which the two brothers worked together for the development of the State of Qin
After the death of Duke Zhuang of Qin, Yingkai became the sixth generation of qin's family lords, and was later known as the Duke of Qin Xiang. However, Qin Xianggong's elder brother Shifu was unfortunately taken prisoner during the battle against Xi Rong.

Qin Xiang opened the country
This situation occurs in other countries, and as a monarch, he must find a way to kill the foreign contenders for the throne. If the contender for the throne is captured, the monarch will not only not rescue him, but will even threaten the other party to kill the contender for the throne. After Duke Huan of Qi ascended the throne that year, he forced Lu Guo to kill his brother Gui.
However, Qin Xianggong not only did not ignore his elder brother Shi Father, but did his best to save Shi Father. Duke Xiang of Qin first married his sister to King Feng of Xirong, and then sent money for King Feng to negotiate with other tribes in Xirong.
Finally, after more than a year of hard work, Qin Xianggong rescued his brother Shi Father.
The Qin people's practice of this kind of practice was not seen at all in the Central Plains countries that talked about the ritual music system. At that time, the Jin state was undergoing a 70-year-long civil strife, and this incident of replacing the large emperor with Xiaozong was later called Quwo Daijin.
In 745 BC, Ji Shicheng was enfeoffed by the Marquis of Jin Zhao in Quwo, known as Quwo Huanshu. Jin Chen's father Killed Marquis Zhaohou of Jin and greeted Qu Wo Huan's uncle, but the Jin people rebelled, and Qu Wo failed to seize the throne.
Qu Wo Zhuang Bo, the son of Qu Wo Huan, sent people to successfully assassinate the Marquis of Jin, and the other princely states assisted Emperor Dazong of jin, qu Wo failed to seize the throne; Qu Wo Zhuang Bo bribed the Zhou royal family and joined forces with other princely states to drive out the Marquis of Jin, and the Later Zhou Dynasty woke up and fully supported Emperor Dazong of Jin, and Qu Wo failed to seize the throne.
Qu Wowu Duke, the son of Quwo Zhuangbo, attacked the capital of Jin and killed the Marquis of Jin, and the Jin people made Xiao'er, the son of the Marquis of Jin, a prince; Quwo Wugong seduced the Marquis of Jin and killed him, and Zhou Tianzi ordered the princes to rescue The Jin Dynasty, and although the Duke of Quwowu failed to seize the throne, his strength had surpassed that of the Jin Dynasty.
Yicheng was the capital of the Jin Dynasty
Duke Wu of Quwo once again rebelled against Emperor Zhengzong of Jin, killing Marquis Zhen of Jin and bribing the newly established King of Zhou with treasure artifacts. The king of Zhou, who had benefited, appointed Duke Wu of Qu as the Prince of Jin, as duke of Jin.
Quwo Xiaozong killed the six kings of the Jin dynasty in a row and became the new zhenzong of the Jin kingdom. However, the civil unrest did not end there, and the son of Duke Wu of Jin, Duke Xian of Jin, began to kill and kill, first the descendants of the marquis of Jin Zhao, and then the clan of The Duke of Jin wanted to dream of Qu Wo Dai Jin Mei, and the Duke of Jin Designed to kill Qu Wo Huan Uncle and other descendants of Qu Wo Zhuang Bo, since the rest of the Gong clan of the Jin Dynasty disappeared forever.
Later, the Jin dynasty was weak, and the root cause of the Jin dynasty's successive seizures of power was Quwo Daijin. At the end of the Spring and Autumn Period, the division of the three families into Jin also became the inevitable end of the Jin dynasty.
