Two wise men came up with a way to throw stones into a ditch from two mountains respectively. If two stones can touch each other, it means that God recognizes them as husband and wife. As a result, in the case of extremely low probability, the two stones finally really combined, and Fuxi and Nu Wa also got married naturally, thus giving birth to Chinese civilization.
According to legend, the red veil is used to cover up the shame when getting married, just to avoid the embarrassment of brother and sister. This marriage custom has been handed down.
In fact, Fuxi married Nuwa in order to reproduce. Judging from the legends of Nu Wa and Fuxi, there are also loopholes. The legend of Nu Wa's creation is familiar. At first, she created human beings from yellow mud. According to this statement, Nuwa should be much earlier than Fuxi, and it is impossible to be brother and sister with Fuxi.
So, why are there two different versions in ancient legends? The author thinks that we should refer to the historical development track, that is, the female society comes first and the male society comes last.
The legend that Nu Wa created man should be born in the matriarchal society, and the marriage between Nu Wa and Fuxi is the existing state of the paternal society.
From a practical point of view, the development and continuation of Chinese civilization cannot be multiplied by any couple. The productivity of ancient society was low, and people lived in groups to resist wild animals and natural disasters. Only two people can't survive and reproduce.
But it is undeniable that the initial stage of Chinese civilization must have originated from the ingenious inventions of our clever ancestors. They have advantages over other races, which makes Chinese civilization the most splendid civilization system in the world and continues to this day. This is great.
