At the end of the Han Dynasty, Cao Pi adopted Chen Qun's suggestion, established a nine-level Zheng Zhi system, and the gentry further monopolized official positions. Although the Sui Dynasty launched the Imperial Examination, it did not break the gate valve, and they were still active in the ruling and opposition parties. These gate valves hold so much power that even the royal family dare not marry easily.
The marriage between the royal family and the lady of the gate is nothing more than to consolidate power. Although the marriage between the royal family and the gate valve is understandable, it will inevitably cause suspicion. In the history of China, among all the prominent aristocratic families, only five are the most prominent, which is the so-called "five surnames and seven expectations".
Li: Longxi Li and Zhao Junli.
Plum in Longxi, which can be traced back to Zhuan Xu's grandson, is located in Longxi, or started in the State of Qin. When Longxi was the satrap, the second son was the southern satrap, and Sun Lixin was the general, and he was named the Hou of Longxi. The Li family in Longxi has been a big official since the Southern and Northern Dynasties. Li Yuan destroyed the Sui Dynasty and established the Tang Dynasty, and the Li family also created a prosperous time.
Zhao is a branch of Ji Li after Longxi. His ancestor is Li Qian, and he is Li Chong's brother. Li Mu, the son of Li Qian, was one of the four famous soldiers in the Warring States Period. Although Zhao did not establish a country like Li Yuan in his development, there were nine prime ministers in the Tang Dynasty.
Cui Shi: Qinghe Cui Shi, Boling Cui Shi.
Cui's surname originates from Jiang's surname, which is a descendant of Emperor Yan. After uncle B succeeded to the throne, his descendants were enfeoffed and changed their surname to Cui. Cui Shi is a noble family of Qi, for example, Cui Yao is the minister of Qi. After the Qin Dynasty, Cui Yao's descendants were named Donglai Hou, and his son Cui Xijue settled in Wucheng in the east of Qing Dynasty.
The two Cui surnames flourished and got Cui Shi in room 10, making a total of 29 prime ministers. Cui Shi is also recognized as "the first hall in the world and the first northern Hao family".
Lushi: Lushi of john young.
Lushi is also the origin of the surname Jiang, a descendant of Qi State, and also changed his surname from a fief. There was a doctor in the State of Qin, Lu Ao, whose descendants took john young as their county, and later called him "Yang Fanren". Lu Zhi, the ancestor of Lu, revealed the Eastern Han Dynasty with Confucianism and established a family business. Lu Yu in the Three Kingdoms was common in Cao Wei, and he was the first to enter the DPRK, so Lu gradually became known as the first class in the North.
Even though the Northern Wei Dynasty was torn apart, the descendants of Lu still served as emperors of the Western Wei Dynasty, the Northern Qi Dynasty and the Northern Zhou Dynasty, and produced eight prime ministers, known as the "Northern Crown Family".
Wang: Taiyuan Wang
Like many gentry, the ancestor of the Wang family in Taiyuan can be traced back, but the real historical research can only be traced back to Stuart in the Eastern Han Dynasty. The reputation was not obvious in the Han dynasty, and it flourished only after the Wei, Jin, Southern and Northern Dynasties. In the Tang Dynasty, some top poets appeared in Taiyuan, such as Wang Bo, Wang Zhihuan, Wang Changling and Wang Wei, and seven prime ministers were born.
Zheng: Xingyang Zheng
The Zheng family in Xingyang originated from Zheng Dang, a great Sima in the Western Han Dynasty, and settled in Kaifeng County, Henan Province. Kaifeng County belonged to Xingyang County in the Western Jin Dynasty, so "Xingyang Zheng" appeared. It is worth mentioning that Tang Wenzong tried to betroth the granddaughter of Xingyang Prime Minister Qin Zheng to the Prince, but was rejected. Qin Zheng married Cui Jia.
Tang Wenzong also sighed: "The son of heaven is 200 years old and can't take care of Cui and Luye." ? Tang Wen couldn't complete the marriage, and the emperor of the Tang Dynasty was naturally afraid of the marriage of these big families. Starting from Li Zhi in the Tang Dynasty, the imperial edict prohibiting marriage was issued, which prohibited "five surnames and seven expectations" from marrying each other.
