There are four sources of Zhào's surname:
1, judging from the surname, the ancestor is Zhao Fu. According to legend, Zhao Fu once got eight swift horses in Huashan and presented them to King Mu. King Mu went hunting in these eight carriages and went to Kunlun Mountain. The Queen Mother of the West gave a banquet in Yaochi. At this time, Xu Yanwang in the southeast rebelled. Zhao Fu drove thousands of miles every day, got back to the Imperial City in time, and led troops to defeat Xu Yanwang. Because of Zhao Fu's rebellion, Mu Wang made him Zhao Cheng (now the north of Hongdong County, Shanxi Province). From then on, Zhao Fu and his descendants took the fief as their surname and became Zhao.
2. Take the country as the surname. Zhao Fu's descendants elected their father to serve Zhou Xuanwang. My father gave birth to my uncle. Because Zhou Youwang had no choice, he left the Zhou royal family and went to Jin as the royal family. In this way, Zhao entered the state of Jin and later became a doctor. When Zhou Weilie was king, he was listed as a vassal. The founding monarch, Zhao Liehou, was a descendant of Zhao Shuai, a doctor of the Jin Dynasty, and was one of the Seven Heroes of the Warring States. After being destroyed by Qin, the Duke of Zhao was named after the original country and became Zhao.
3. It is the surname of ethnic minorities. There are also ethnic minorities named Zhao in history, such as Zhao Anji (Xiongnu) in the Han Dynasty, Zhao Tufu (Naman) in the Tang Dynasty, and so on. Their descendants all take the surname Zhao. In addition, the Mongols want to change their surname to Zhao.
4. Zhao Song gave his surname. There were historical figures with the surnames of Li, Mu, Long and Yuwen, who were given the surname Zhao.
Ancestor: jujube father. Shao Hao was a famous horse trainer in the Western Zhou Dynasty. Fortunately for Zhou Muwang, it is said that he once took eight good horses to the king and went west to Kunlun, where he met the Queen Mother and forgot to come back. After hearing the news of the rebellion in Xuzhou, he personally rode in a royal chariot, carrying the King Mu thousands of miles a day, and returned at the right time, putting down the chaos and being sealed in Zhao Cheng (now Zhaocheng Town, Hongtong County, Shanxi Province) as a hero. After it spread to Zhao Xiangzi, it was divided into three parts with Korea and Wei, and established Zhao, which was destroyed by Qin in 222 BC. Later generations took the country name as their surname, called Zhao, and respected Zhao Fu as their ancestor.
Second, migration distribution.
Zhao was born in today's Shanxi Province. At the beginning of Qin dynasty, the first emperor appointed Zhao Gongfu as the chief executive of Xirong area and lived in Tianshui. Their descendants settled in Tianshui, and soon they became a prominent local family. At the same time, Wang Zhao Zhao Qian was exiled to Fangxian County, Hubei Province, where his descendants were born. After the establishment of Nanyue State in Zhao Tuo, Zhao was promoted to Guangdong and Guangxi today. Zhao's southward migration began in the Three Kingdoms period, and the Northern Song Dynasty established by Zhao in the county made Zhao's population develop unprecedentedly. The Southern Song Dynasty established by Zhao made the Zhao family flourish in the south of the Yangtze River. At the same time, Ye Zhao in the north was moved to three northeastern provinces. Since the Song Dynasty, the surname Zhao has spread all over the country.
The word seniority depends on which branch you belong to. Every branch is different, and it is difficult to generalize. You can ask your parents for details.
