Why are these hundreds of surnames arranged in the order of Zhao, Qian, Sun and Li?

Surname is an important part of China culture. The ranking of the former hundreds of surnames such as Sun Zhao, Li, Zhou, Wu, Zheng and Wang was entirely due to the influence of family politics at that time, which can be seen from the articles of scholars at that time. In the Song Dynasty, A New Record of Jade Photos recorded: "If Hundred Family Names were printed on the street, (Wang) tried it in the Ming and Qing Dynasties in detail, so it was written by Wang when the Qian family in Zhejiang had a state. What? Its first cloud' Qian Sun Zhao Li', Gai Qian's surname is Zhengshuo, and Zhao Ben's surname is Chao Guo, so money is second; Sun Naizhong Yi (money) is a princess; Secondly, Jiangnan is leeward. In the second sentence, the cloud' Wu Zhou Zheng Wang' all died. " Therefore, the order of hundreds of surnames is arranged according to the surnames of the imperial rulers at that time. "Zhao" was the surname of the emperor at that time, and naturally ranked first; At the beginning of the Song Dynasty, other regimes still existed, such as King wuyue of Zhejiang and Li Yu, Queen of Southern Tang Dynasty in Jinling (now Nanjing), so "Qian" and "Li" ranked first. It is said that the author of Hundred Family Names is from Qiantang, Zhejiang Province, so he ranked the surname of the former princess and grandson of Chu before the surname of the Southern Tang Emperor Li, forming the order of "former grandson". And the next "Zhou Wuwang" is the surname of other concubines of the former Chu and his father's concubines.
