The dragon surname is Ao, and the phoenix surname is Luo, which is the Lei ancestor. Dragons and phoenixes are both totem cultures that appeared in our ancient Shanggu tribe period. And at the beginning, the image of the dragon was not fixed. It was not until the Western Han Dynasty that the image of the dragon was fixed, and it became the four-clawed golden feet with fish scales we see now.
Because in the ancient tribal period, Emperor Xuanyuan unified all the tribes. In order to let everyone have faith, he created a totem culture. Emperor Xuanyuan asked everyone in the tribe to offer their own totem. Finally, the images of dragon and phoenix were formed. The dragon represents the king, and the phoenix represents the queen. And when we watch some film and television works, we can find that the surname of the dragon family is Ao, and the surname of Phoenix's descendants does not appear. However, if we calculate based on the records in ancient books, the surname of Phoenix's descendants is Lei, that is, Leizu, the wife of Emperor Xuanyuan.
When the dragon totem was being made, many people were dissatisfied with the totem and felt that the elements they contributed were not used. Emperor Xuanyuan was also very distressed later, but his wife Leizu made it for her. I came up with an idea, which was to create a new totem using the elements presented by the previous tribal leaders. So in order to balance everyone's psychology, he once again created the Phoenix totem using other elements. Because his wife told him this idea, he named it after his wife's surname. That's why dragons and phoenixes appeared, and we have totem worship.
Now we can also see that there are very few people with the surname Ao. They are the descendants of the Dragon clan, and there are even fewer people with the surname Leiluo, and after evolution, Leiluo has become It became "Thunder", which is the thunder of thunder and fire from heaven and earth. But because there are no specific historical records, these are all based on our speculations, and we cannot be sure. Whether the descendants of Phoenix are surnamed Lei is because there is no such record in many ancient books and records.
