Article 348

Then the divination of "returning to the sister" can be understood as that the wise Shang Zhouwang married his sister to the ruler of Zhou in order to bridge the political relationship between the Shang and Zhou families that was on the verge of rupture. It can be said that this is an early and famous marriage event in the history of China. I didn't say the earliest, because, I'm afraid, in ancient times, affinity was a common practice. For example, Emperor Yao married his daughter and Shun, which was actually a means to pull relations. As for why Emperor Yao married his two daughters to Shun at once, it involves the custom of ancient aristocratic marriage, which is called the concubinage system, that is, to marry a woman as a housewife, and the rest of her sisters should also take concubinage with the past.

In any case, this marriage ushered in a new period of good relations between Shang and Zhou dynasties. Although the two major political groups in Shang and Zhou dynasties have not yet resolved the compromise of their opponents, it is enough for the people of Shang and Zhou dynasties who love peace to deeply appreciate and miss it.

So, what does the Book of Changes want to explain with this historical event? "Your beauty means the meaning of heaven and earth." It is a matter of course for women to get married, which is a great event for men and women in their lives. It runs through a person's life, and husband and wife should grow old together like guests. If one party violates the righteousness of husband and wife, or plays an improper role, or bullies the weak, or even destroys the stable relationship of marriage at will, it will inevitably bring disaster. It is inappropriate for haiku to explain "levying fierceness"; "No advantage", taking advantage is also soft.

There is a slightly far-fetched saying that "back to your sister" is homophonic with "ghost", which may be a vague warning to people not to engage in unpopular intrigues in secret, otherwise it will harm others and themselves. Conversely, it is also a warning to gentlemen: although evil is small and not done, it can avoid disaster and take refuge.

And he said, "Go back to your sister, people will always be the same." Finally, we should carry out the spirit of "the gentleman knows the other", be loyal to the right path, and guard against the damage of the unchanged marriage relationship between men and women. It enlightens people that they will be bound by certain social norms in social life. The necessary discipline and system is to maintain order and create an optimized environment. Although these systems will make people uncomfortable, obedience and cooperation are really necessary, and only in this way can we relax within a certain limit.
