Before talking about this legend, we must first understand what " Guanlong Group " is?

1. Guanlong Group
. Before the Sui Dynasty Emperor Wen of Sui , Yang Jian unified the world, the land of China was divided into Southern and Northern Dynasties . The north experienced several countries and was relatively chaotic. Among them, Northern Dynasties (386-581) inherited from the sixteen countries and was established by Xianbei , including the five dynasties of Northern Wei, Eastern Wei , Western Wei , Northern Qi and Northern Zhou.
The later Sui Dynasty and Tang Dynasty were actually behind the Xianbei people. Among them, the Yuwen family established Northern Zhou , the Yang family established Northern Zhou , the Yang family established cherrymanders to unify China, and the Li family overthrew the Sui Dynasty and created the prosperous Tang Dynasty. Now it is said that the Tang Dynasty is relatively open, but that is because the rulers are the Xianbei people, and the Xianbei people have the shadow of matriarchal clans. If it were the Han people at that time, it would not be so open. It is not that the Han people are not as good as ethnic minorities, but that the Han people are too tightly bound by Confucianism .

Dynasties
The strong rise of the Northern Dynasties, and military groups that had a profound impact on Chinese history all belong to the Guanlong Group.
2. Political marriage
In order to consolidate the alliance relationship between each other, the Guanlong Group firstly guarantees each other in military and political terms, and secondly, a special political bond was established through marriage.
There is a key figure in this link, which is , one of the eight pillars of the Western Wei Dynasty, , Da Sima, , Dugu Xin.

Dugu Xin has seven daughters, and the eldest daughter married the eldest son of Yuwen Tai , that is, Emperor Ming of Northern Zhou Yuwen Yuwen Yu.
Seven Girls Dugu Jialuo married Yang Zhong's son Yang Jian, who later Emperor Wen of Sui. Now, the Gala Sagittarius in a mobile game in China is Dugu Jialuo. He is very talented and has helped Yang Jian a lot in national governance. The couple is called the "Two Saints".

Dugu Jialuo
Four daughters married Li Hu's son Li Bing , and later gave birth to Li Yuan . Later, after Li Yuan established the Tang Dynasty, he posthumously respected Li Bing as Emperor Yuan, and Li Yuan's mother was naturally posthumously named the queen.
Therefore, Dugu Xin became the father-in-law of the three emperors, and the Gudu family became a unique family.
This is the story of the famous Three Queens, and there are no ones who have ever been there before.
