The Classic of Mountains and Seas records that Wang Hai was in a position to be a servant of cattle, killed and finally dismembered, but lacked a complete storyline, fortunately, Qu Yuan, who was extremely talented in literature, described many details of this matter as if he were a witness and described many details of this matter in a vivid way, as mentioned above, was Wang Hai's violation of the marriage taboo his inadvertent act or was there another black hand behind it?

A panoramic view of the biography of the King of Zhou, a view of the mountains and seas
(1) His brother Wang Heng
"Heng Bing Ji De, Yan Defu Servant Cow?" ...... Dizziness and adultery, endangering brother" - "Chu Ci Tianwen"
It is very interesting that in Qu Yuanzi's "Heavenly Question", there is a "Heng" character, which is obviously supposed to be a person's name, so who is this mysterious person? What role did he play in Wang Hai and Youyi's affairs?
Wang Hai
Judging from the words in front of it, "The Bingjide, the father is Zang", "the" refers to Wang Hai, so according to the same linguistic logic, the "Heng" in this sentence "Hengbingjide" may refer to his brother Wang Heng. The reason why it is considered to be his younger brother, because there is also such a sentence in the back, "Dizziness and adultery, harming brother", it is obvious that the murdered Wang Hai can only be the elder brother, then Wang Heng is naturally the younger brother.
That is to say, when Wang Hai went to the land of Youyi, he was not alone, and his brother Wang Heng was also accompanied by him. Then, when Wang Haidong was killed by Yi Yi in the East Window incident, where was Wang Heng? What's he doing?
"Bamboo Book Chronicle , Volume IV" Yun: "In the twelfth year of Emperor Xia's release, Marquis Yin's son Haibin was easy to kill, and he let it go"
Here," "there is something easy to kill and let go" is very suspicious, since Wang Hai was killed, how can it be released again? Judging from the final result, Wang Hai was indeed killed, and it could only be his younger brother Wang Heng who was released. Such a result is somewhat intriguing. Since Youyi had already torn his face with the Shang clan and decisively killed Wang Hai, why was his brother Wang Heng able to stay out of the matter and be released unharmed?
Wang Hai serves cattle
"Heng Bing Ji De, Yan Defu Servant Cow?" Where to camp Ban Lu, not only to come back? ——" Chu Ci Tianwen
From this sentence, no matter how you look at it, Wang Hengdu looks like the black hand behind this matter, after all, no matter how you look at him, he looks like the biggest beneficiary: not only did he get his brother's wealth servant cow, but he also came to Youyi Juju Shilu, and even married his brother's woman, which was the daughter of Youyi who Wang Hai danced and picked up.
(2) There is a daughter of Yi
The so-called red face disaster in history is often innocent. When fate reaches out and sows the seeds, everything will grow wildly like weeds and can no longer be controlled.
"Dance when you do it, why do you think of it?" Flat skin, why fattening it? ——" Chu Ci Tianwen
When they first met, Wang Hai made you fall in love with a majestic and provocative dance. The daughter of Youyi is indeed good-looking, so Old Master Qu described: A woman with a plump body and smooth skin, why do you look so white and beautiful?
"Where is the cloud?" Strike the bed first, where is its life? ——" Chu Ci Tianwen
Just because it is really good to have a daughter of the Yi tribe, Qu Yuan said: Wang Hai, you are a boy with yi herding, how did you meet her?
In fact, this yi woman was not only good-looking but also very clever, and when she was caught in bed with Wang Hai, she cleverly escaped first. So Qu Yuan continued to ask: What is her fate in the end?
"What bird to pluck thorns, negative son to be reckless? Dizziness and adultery, endangering the brother. ——" Chu Ci Tianwen
All in all, the ultimate fate of Youyi's daughter is indeed a twist and turn, according to Qu Yuan, "Di Di Di" refers to the younger brother Heng who confused Hai, and "adultery" means that the brothers share a wife, that is, after Wang Hai's death, Youyi's daughter became Wang Heng's wife. Not only that, after Wang Hai's son Shangjia Wei defeated Youyi, he also married this youyi's daughter, which is the so-called daughter of the son and wife.
Lineage of the Shang kings
Now that I think about it, this matter is also extremely bizarre, so is it reasonable in the social situation at that time?
(3) Inheritance system
There are Yi also that is, there are Hu, Youdi, and Youyi belong to the same clan as the "Youluo clan", and the female ancestor of Yin Shang is from the "Youluo clan", called Jiandi, Mr. Yu Shengwu said: "The Shang Dynasty maintained a marriage relationship with the Youluo clan from the ancestral mother Jiandi to the Yixin period." In fact, the relationship between the Shang clan and Youyi has always been more complicated.
Destiny Bird
Wang Hai's "Guest yu Youyi" shows that Wang Hai still adopts the "ju-woman's family" system of coupled marriage in the matriarchal society of the Yi clan in the marriage relationship of The Yi clan, in this case, in order to marry the daughter of The Yi back to the clan, in addition to paying a certain dowry to the woman's clan, Wang Hai often has to serve in the woman's family for a period of time as a way of economic compensation for the woman's family, so he calls Wang Hai "Youmu Shu".
Living in a woman's house
At this time, the Shang clan was already in the stage of shifting from matriarchy to patriarchy, and one of the consequences of Wang Hai's son-in-law was that after Wang Hai's death, the cattle property he owned could only belong to the female clan. Obviously, this is unacceptable to the Shang clan. Therefore, Wang Hai's brother Wang Heng once again returned to Youyi, wanting to claim the wealth that Wang Hai deserved, and marrying the daughter of Youryi who married his brother also meant another strengthening of patriarchy.
Quotient with birds
Until the end Wang Hai's son Shangjia Wei attacked and occupied Yi, in accordance with the inheritance principle of father's death, brother and brother, he married his stepmother, marking the complete failure of the matriarchal system of "husband from wife", starting from Shangjia, the Shang clan began to marry foreign women into their own clan, the Shang chief began to accurately calculate the lineage according to the patrilineal lineage, the establishment of "ancestor" and "concubine", and also opened the transformation of the Shang clan from a dual family like a monogamous system.
