In the pre-Qin period, the change of dynasties could destroy the country, but it could not cut off the ancestral hall, especially the Shang Dynasty had a history of 500 years, and the founding king Shang Tang was known as a "saint".
Therefore, when King Wu of Zhou divided the princes, he still let Wu Geng, the son of King Shang, manage the merchant land and merchants.
After the death of King Wu of Zhou, Wu Geng launched the Rebellion of the Three Prisons, and Zhou Gongdan summed up the experience after quelling the rebellion, the shang land was too large, there were too many merchants, and it was always a huge threat.
Therefore, the Shang kingdom was divided into two, part of which was administered by his younger brother Uncle Kang to establish the Wei state; and part of which was handed over to the administration of Wei Ziqi, the eldest brother of the King of Shang, to establish the Song state.

In 710 BC, the Song dynasty ushered in the first coup in its history, which was caused by the wife of a minister who was too beautiful.
The military commander of the Song Dynasty, Kong Father Jia, had a beautiful wife, how beautiful was it? It is not specifically documented in the literature, but it is evident from the descriptions of other populations.
This person is not an ordinary person, has a high status, has met many women, he is the Song Dynasty Prime Minister Hua Du.
One day, Hua Du met Kong FatherJia's wife on the street, and he was shocked for a while, and he simply looked like he had lost his soul.
It is recorded in the "Records of History", "Sima Kong's father and wife were good, and when he made his debut, he met Dazai Huadu, and the governor said that he looked at it with his eyes." ”
When the woman walked away, Hua Du returned to God and said three words, beautiful and beautiful.
The "Left Biography" has a record, and the eyes are sent against it, that is: beautiful and beautiful.
With Hua Du's position in the Song Dynasty, it was not difficult to get a woman, and after some inquiry, it was not good news, and the woman was Kong Father Jia's wife.
Kong Father Jia was the military commander of the Song Dynasty, not an ordinary cat and a dog, but in order to get the beauty, Hua Du still decided to attack Kong Father Jia.
And Kong Father Jia as a military commander did have problems, the soldiers want to win the war, but after he took over the army, the war was fought a lot, but there were almost no victories.
Fighting and burning money, defeating the war and burning money, the people were miserable, so Hua Dou took the opportunity to slander Kong Father Jia, instigate soldiers to mutiny, and provoke the people to resist, and as a result, Kong Father Jia was killed.
The people of the Song Dynasty all knew that Kong Father Jia and Hua Du were at odds, and it was not surprising that the two of them fought each other, but for a woman, the tragedy of "killing the general" actually occurred, which was both absurd and outrageous.
Hua Du knew that Duke Song was not accustomed to himself, and he was bound to give a fierce hand, so he did not stop doing two things, and then killed Song Duke, and then welcomed back Gongzi Feng from Zheng Guo, and established him as the prince of Song Guo, known as Song Zhuang Gong in history.
The "Records of History" records that "the Duke of Yinggong was angry, so he killed the Duke of Death, and Feng Yuzheng, the Prince of Yingmu, was established for the Duke of Zhuang." ”
From the perspective of later generations, this story seems to be a usurpation incident triggered by a woman, but it is not so simple, but has a deep political background.
In 729 BC, When Duke Xuan of Song died, he did not pass the throne to his son Andyi, but to his younger brother He.
The "Chronicle of History" records, "Nineteen years, Xuan Gong fell ill, let his brother and peace." ”
The reason is very simple, the Song Kingdom was founded by the descendants of Shang Yin, and the merchants had the habit of brothers and brothers. In a way, the younger brother's succession to the throne is just a matter of addiction, and in the end it must be passed on to the brother's son.
Song Xuangong's younger brother was initially reluctant to accept it, and only agreed after resigning three times, and after Zihe ascended the throne, he was known as Song Mugong.
In 720 BC, Song Mugong was seriously ill and knew that he was about to die, so he summoned the army commander Kong Fujia to return the throne to his brother's son Youyi.
Father Kong persuaded that most of the courtiers hoped that their son Gongzi Feng would become a monarch. However, Song Mugong still insisted, otherwise he would not have seen the ancestors and ancestors, and at the same time, he also wanted Kong Father Jia to protect and Yi.
It is recorded in the "Records of History", "I dare not forget that the prince of the first emperor Xuangongshe and Yi established me." When I die, I will stand and destroy. ”
In order to avoid civil unrest in the Song kingdom, Song Mugong moved his son Gongzi Feng to the Zheng state. Not long after, Heyi succeeded to the throne smoothly, and was the Duke of Song.
However, the good wishes were still disappointed, and after the death of Song Mugong, two powerful groups that fought each other appeared in the Song Kingdom.
On the one hand, song Yigong, who is supported by Kong Father Jia, and on the other side is Gongzi Feng, who is supported by Hua Dou, and the two sides have been fighting endlessly, and Kong Father Jia's wife is just a fuse.
It is worth saying that Kong Father Jia was a descendant of the Shang Yin royal family, and his descendants escaped from the Song Kingdom, and one of them settled in the Lu Kingdom, changed his surname to Kong, and a hundred years later, Kong Qiu was born.
