"When time went back a long time, it was about 3.1 million years from now. The breeding and planting industries in various places have initially reached a scale, so that agricultural production has developed greatly, people have passed the difficult era of frequent hunger and fullness, and people have also climbed up from the low end of the biological chain. Ideologically, I feel that competition with alien animals is not so important, and gradually evolves into competition with the same kind, and puts a lot of energy into seizing the interests of others. At this time, the human brain has also reached a certain stage of development, and this development is still limited to thinking for one's own interests, focusing on satisfying personal needs and thinking about how to live comfortably, so I call this period of human wisdom 'shallow wisdom period'.

When people develop a sense of self-awareness, they begin to change from the struggle against the natural environment and the struggle against external alternative animals to the struggle between tribes and internal struggle for interests. I understand this 'selfishness' to be shrinking and then expanding. To say that it is shrinking is to say that in the age of ignorance, people have a strong sense of helping each other and giving to each other in order to survive. When the sense of assistance is weakened, people will be indifferent to the consciousness of mutual dedication and begin to enjoy themselves, and the 'selfishness' will expand infinitely and manifest itself in all aspects. But it is mainly the birth of the family that lays the soil for the breeding of 'selfishness', and all kinds of 'selfishness' take root, sprout, grow leaves, and bear fruit in this soil.

Let's talk about our lovely ancestor '娈', her whole life is to fight for a small group, and make unremitting efforts for everyone to survive safely.

Even in the era of 'Difu', she has made such great contributions, but she is still not selfish and wholeheartedly works for the welfare of the people in the group.

In addition, in the era of 'leaning' and 'heavy weight' and 'Zhuang Xi', they were all 'small self' and 'big group', and they didn't think about themselves wholeheartedly. Of course, it was not that their ideological realm was noble, but that the external forces were very strong, forcing people not to fight for themselves, because no matter how smart you are, you can't stand against the powerful external forces by relying on your own strength. Everyone understands a truth, that is, we must work together and unite to form a stronger force and protect everyone's living space through weal and woe.

It was only in the era of 'Hengjiao' and 'Miser', when external forces were no longer the main problem endangering human existence, that people began to pay attention to the interior, began to fight inwardly, and began to have a sense of family, which was later further narrowed down to family consciousness. I also performed a short story, which is the process of transforming family thinking into family thinking;

After 'Mi Hui' foiled 'Yu Kun''s plot to kill him with the help of 'Mi Kun', he valued his own brothers very much and put 'Mi Kun' in a position second only to himself. After that, 'Mi Hui' and 'Xu Li' gave birth to 3 boys and 3 girls, all of whom survived due to their privileged lives, plus the 10 children they had with other women before. 'Mi Kun' also had seven or eight children with several women, and these people were all given special care by 'Mi Hui', living in a relatively wealthy environment, and the family was very strong. Everyone is also very united in order to protect their own interests, and also consolidates the family privileges.

'Mi Hui' died at the age of 46 and his eldest son, 'Mi Hao', took his place. At this time, the 'miserliness' also stipulated in consolidating the family that both men and women in the family should have a fixed wife or husband in order to produce offspring that are all related by blood. After several generations of reproduction, the family has more and more people, and gradually eliminated the distant branch seedlings, not allowing them to enjoy the same treatment, and later developed to the point that it is not a direct line, such as children and grandchildren are not allowed to enjoy the highest treatment, so that the superior treatment of the family replaces the superior treatment of the family, and begins to form a family.

After the birth of the family, people will do everything possible to accumulate wealth in order to keep the family rich. In the soil of the family, various ideas of private ownership began to grow, such as the unscrupulous plundering of wealth; Treat children as private property; Treat your home as your own and the rest as someone else's; Even powerful people say this: 'What's mine is mine, yours is mine, everyone's should be mine' extreme selfish thinking. The expansion and development of such ideas and concepts has evolved into the point that the self can take advantage of it; Double-cross each other; seizure by force; murder for profit; abduction; Unfaithlessness, unrighteousness, and other vices and vulgarities.
