So, let me start with this: I have been thinking recently about the cultural differences between the three kingdoms of gods in Dahuang. According to what is shown in the drama, in Xiyan, both men and women should have their hair tied up, in Haoling, both men and women should wear their hair loose, while in Chenrong, hair can be tied or let loose at will. The Xiyan Kingdom seems to regard black/dark colors as noble, while the Haoling Kingdom values white as noble, and people like to wear light-colored clothes.
The Xiyan Kingdom advocates law and force, the Haoling Kingdom pays attention to etiquette and hierarchy, and the Chenrong Kingdom values family and lineage.
Also, below is what I imagined:
Haoling's industry and commerce are developed, so it is rich. Chenrong's agriculture is developed, so it has a large population. As we already know, the military of Xiyan is the most developed. Judging from the eating habits, the animal husbandry of this country should be developed.
The drama only shows that people regard the gods as noble and the demons as humble, but it does not elaborate on this. According to the laws of some foreign occupation periods in Chinese history, I think gods, humans, and demons in Dahuang may also be legally unequal. For example, if a god kills a demon without reason, he must only be demoted and pay compensation, while if a demon kills a god, he/she will be punished with death, and so on. Intermarriage between different races are not allowed either. But given that King Xiyan is the founding king of Xiyan Kingdom and he has the idea of equality, I think Xiyan Kingdom may have looser laws in this regard, such as allowing citizens to change official races by merit/contribution (like the demon General Ying Long who "turned into a dragon"). In addition, the relationship between races in Qingshui Town should also be more equal.
If this is the case, then this may be one of the reasons why Xiang Liu has lived for hundreds of years but still can only be a playboy: in my understanding, there should be no sexual attraction between demons of different species (even if they can all take human form, their smells must be different), otherwise, what kind of child will be born? ? A bull will not be interested in a mare, and similarly, a hydra demon will not be interested in an ordinary snake demon. This determines that it is impossible for Xiang Liu to find a wife among his own race, because we already know that he is the only known nine-headed snake in Dahuang, truly has no companions. Although he can have non-serious dates with female gods or women when pretending to be FFB, such relationships cannot last long, or there is a risk that his true identity will be exposed. And even if these women have feelings for him, he won't take it seriously because they don't know he is actually a demon and wanted criminal. Moreover, because he is destined to be enemy of Xiyan/wanted criminal, he cannot rely on his skills to improve his status and marry a god/human. Xiaoyao was the first woman he approached as Xiang Liu, so at first he had no idea what to do.
According to Chinese mythology, the human population should be the largest in Dahuang, followed by demons, and the number of gods is the smallest, and most of gods have traceable blood lineages, which is consistent with the background in the drama. Although the population of gods is small, the three kingdoms in the play are called "Kingdom of Gods". From this, it can be inferred that gods should be the ruling class. Most gods serve in government departments, the army, the public security system, the legal system, and the education system, ruling all living things in Dahuang (CX once mentioned to XY that "our grandmother is in charge of all silkworms and mulberry trees in the world"). Because demons are legally discriminated against, they are more likely to be demoted into slaves. Therefore, although the number of demons is far less than that of humans, their proportion among slaves is not low (I speculate that Xiang Liu may have been arrested for hurting a god or human for some reason when he was a child, so was demoted to slavery). According to the law, gods are prohibited from being demoted to slavery. If a god commits a serious crime, he/she will be killed directly.
So, guys, any opinions or additions, please? :-)
