In "Zhou Yi", there is "Gui Mei" 卦, which is called "Gui Mei: Conquest, No Profit". The lower and upper shocks overlap each other, "there is the movement of marriage, there is the image of marrying a woman, so it is called a return sister."
In fact, this gua is taken from the historical fact that Emperor Yi of Shang (the father of the King of Feng) married his sister to King Wen of Zhou, and this affair was also rumored to be a beautiful talk for a while, and the history called "Emperor Yi returned to his sister".
It turned out that in the late Shang Dynasty, the national strength gradually declined, and at this time, the next Ji clan in the Western Qishan Mountains, the Zhou, began to rise. According to the "History of Zhou Benji", the ancestor of the Zhou clan was the father of the ancient gong, and he had three sons: Taibo, Yu Zhong, and the younger son Ji Li, and the son of Ji Li was the later King Ji Chang of Zhou.
According to legend, Ji Chang was born with Xiangrui, and Gu Gong's father thought that he would become a great instrument in the future, so he intended to pass it on to his father Ji Li. Taibo and Yu Zhong understood their father's thoughts, so they went to the land of Jingbaran and, according to local customs, cut their hair short and tattooed them with patterns on their bodies, indicating that they wanted to give way to their younger brother Ji Li. Later, Taibo and Yu Zhong founded the State of Wu in the Taihu region.
After the death of Gu Gong's father, Ji Li succeeded to the throne and was called Gong Ji. Sure enough, Ji Li not only inherited his father's policy of ruling the world, but also implemented benevolence and righteousness, vigorously developed agriculture, and the Zhou tribe rose rapidly.
At that time, the monarch of the Shang Dynasty was Wen Ding, and in the face of the increasingly powerful Zhou clan, he could only adopt the strategy of Huairou and make Ji Li a priest, that is, a local chief. And Ji Li did not dare to come rashly, and continued to strengthen various ties with the merchants.
At this time, the Rongdi tribes on all sides saw the decline of the Shang Dynasty's state and constantly attacked the border, but the Shang were no longer able to cope with the battle, and could only endure it again and again.
Seeing that Wen Ding did not fight back, Ji Li immediately counterattacked these Rongdi tribes. He successively conquered Yu Wurong, Shi Hu Rong, and Feng Tu Rong, captured a large number of people, and snatched back a large amount of booty, but Ji Li dedicated these to the Shang king Wen Ding, who was very happy and entrusted the heavy task of guarding the frontier to Ji Li.
As a result, many princes submitted to The Zhou, and the military strength of the Zhou became stronger and stronger. In order to prevent Ji Li from "rebelling", The Shang king Wending suddenly ordered his execution.
After Ji Li's death, his son Ji Chang succeeded to the throne as King Wen of Zhou. Determined to take revenge on his father, King Wen continued to implement the policies of his grandfather and father and actively developed agricultural production, while recruiting talents and reusing people with real talents and practical learning, and at the same time he secretly recruited troops to buy horses and expand military strength.
After Wen Ding's death, Emperor Yi ascended the throne, the thirtieth monarch of the Shang Dynasty. At the beginning of Emperor Yi's reign, Ji Chang actively amassed troops and prepared to avenge his father.
At this time, the Shang Dynasty was also facing the rebellion of Yifang, Mengfang, Linfang and other tribes, the situation was grim, in order to avoid the simultaneous enemy of the east and west, and in order to repair the subordinate relationship between the Shang and Zhou dynasties that was tense because of his father's killing of the Ji calendar, Emperor Yi decided to adopt the method of peace and affinity to ease the contradictions between the Shang and Zhou dynasties, stabilize the overall situation, and hoped that the two major powers of the Shang and Zhou dynasties, who were dependent on each other, would not remember each other and be as good as ever.
Ji Chang was also a shrewd leader, and he judged the situation and believed that the time was not ripe to destroy the Shang, on the one hand, in order to stabilize the Shang King, but also to gain enough time, he agreed to marry the Shang.
The Zhou people called themselves "Xiaobang Zhou" and called shang "Dayi Shang", and now that they can marry the Shang Dynasty, they feel that it is really a "match made in heaven", and the history calls it "Emperor Yi Gui Sister", which was rumored for a while to be a beautiful talk, and shang and Zhou were all happy and reconciled.
Emperor Yi personally went to divination, chose the date of marriage, purchased a rich dowry, and ordered Ji Chang to continue to serve as a Xibo and command the Western princes. On the day of the wedding, in order to show solemnity, Xi Bo personally went to the north bank of Weishui to greet his relatives.
At that time, the scene was described by posterity in the "Book of Poetry • Daming": Ming ming is below, and hehe is above. Heaven is hard, it's not easy to be king. The heavens are suitable, so that they do not threaten the four sides. Zhi Zhongshi Ren, from the other Yin Shang. To marry Zhou, to concubine Yu Jing. It is the journey of Wang Ji, Vader.

It can be seen from the poem that King Wen's yuan match is the "sister of the heavens", that is, the "sister" of the "emperor Yi Gui sister".
After stabilizing Zhou, Emperor Yi concentrated on dealing with the Southeast Yi clan and soon won the victory over Banshi and returned to the dynasty.
Emperor Yi and King Wen succeeded to the throne almost at the same time, according to the oracle bone, Emperor Yi reigned for about thirty years, while King Wen reigned for about fifty years, collapsing in the late period of Di Xin (King Huan), who reigned for thirty years.
During the more than thirty years of Emperor Yi's reign, shang and zhou did not see each other. It can be seen that Emperor Yi Guimei really promotes peace and plays a role in stopping the soldiers.
