Zhang has five surnames: 1, which comes from the same mother and younger brother. After the feudal city as the surname. According to Yuan He's surname code, he is a descendant of Wei Kangshu in the Western Zhou Dynasty. According to the Records of Yuanhe's Canon and Genealogy, after Zhou Wuwang destroyed the Shang Dynasty, he named his younger brother (Zhou Wenwang's youngest son) Kangyi, who was known as Kangshufeng in the world. Wei Kangshu, the word Ji, the younger brother and the ancestor of Wei. Therefore, the Book of Prime Ministers in the New Tang Dynasty says, "Chang's surname is Ji. Uncle Wei Kang's grandson eats Changyi because he thinks his surname. " Later, the Duke of Zhou (his younger brother) sealed the Shangdu area and the seven families of Yin and Min to Kang Shu and established the State of Wei. Wei became a vassal state of Wei in the first 254 years and was destroyed by Qin in the first 209 years. At the beginning of the Zhou Dynasty, the Duke of Zhou wantonly enfeoffed the princes, and the princes enfeoffed the fiefs. Wei Kangshu gave a son a fief in Chang (now southeast of Tengzhou City, Shandong Province). After Wei's death, some of his descendants took the country as their surname, and some took the city as their surname, which was often called authentic in history. At the same time, it is not excluded that the descendants of Yin Shang changed their surnames to Wei or Chang. A common surname in Shandong. 2. Chang Yi, a minister from the Yellow Emperor, and Chang Xian, a great one, are said to have their ancestors' surname Chang. "Examination of Surnames" contains: "The ministers of the Yellow Emperor often take constancy and greatness first, and the constancy should be based on this." According to legend, in the era of the Yellow Emperor five thousand years ago, many ancient people took Chang as their surname. According to legend, the second princess of the leader of Zhou Shangzong is called Chang Yi, who is famous for making good use of the moon, the new moon, the string and the moon. Ji Di said that she was the second princess and gave birth to Zhi Di. Because the ancient words "Yi" and "E" were used at the same time, the story of the Goddess Chang'e flying to the moon in later generations may have been written by Chang 'e. Records of the Five Emperors in Historical Records records that the Yellow Emperor ruled the people by "keeping the wind, strengthening animal husbandry, always giving priority and being big", and was first appointed by the Yellow Emperor as Da Sikong (the official in charge of the project), which is the earliest common surname in history. A Qing Zhang Man said in "The Origin of Surnames": "The Yellow Emperor made Changyi occupy the moon, and sometimes it was a big common first, so it was appropriate to have a surname." Xuanyuanqiu, where the Yellow Emperor lived, was in the northwest of xinzheng city, Henan Province, and the capital of Di Ku was in yanshi city, Henan Province, so China's earliest surname was from Henan. Therefore, Chang's family should be said to have existed five thousand years ago, especially for Chang's family in Henan. 3, from the surname Ji, after the Prince of Wu in the Spring and Autumn Period, took the name of the fief as the surname. According to the research of surnames, in the Spring and Autumn Period, the King of Wu made it a branch of Changzhou (now Changzhou, Jiangsu), and later took the feudal city as his surname, which was the surname of Jiangsu. Another "Chang" surname comes from the descendants of Wu Gong during the Warring States Period, and also from Ji's surname, that is, the Southern Song Dynasty's History of Taoism said that "Wu Zetian had a Chang's surname". According to the surname test, "Wu Zetian has a constant surname". The ancestors of Wu were the uncles of King Ji Chang, and the capital of Ji Chang was in Wu (Suzhou, Jiangsu). However, when and why Wu Gong's descendants were Chang's is not recorded in ancient books, which needs further research. 4, from the constant surname, avoid changing the surname. According to the genealogy, in ancient times, "Heng" and "Chang" were synonyms, located in the north. Because of anonymity, he changed his surname to Chang. The constant surname was originally after the Duke of Chu, and the constant heir was male. This is what Zheng Qiao said in the Genealogy of the Southern Song Dynasty, "Hengbie's family was taboo in the Song Dynasty and changed to Chang's family", which mainly spread in the eastern coastal areas of Jiangsu today. 5. There are common surnames from ethnic minorities: ① Yugu Zongman, Kirgiz Erzike, Tu Changxian, and Han surname Chang. ② Shui, Meng, Man and Hui all have a common surname. According to "Wyeth Studies", "Jin said: Chang Zhi has a beautiful poem, first go to Samarkand ... and then to Jining, and join the local surname. According to Jiangsu Liuhe Chang's Genealogy, the ancestor (Chang) Yu Chungong was born in Yongpinggang, Huaiyuan, Anhui. During the Yongle period of the Ming Dynasty, Zu Taiyun was the governor, and because of his advanced age, he was the ancestor of the Tang Dynasty. " Today, the Hui people in niujie and Flower Market are also called descendants of Chang Yuchun. At present, the Chang people in Changfen Town, Huaiyuan County, Anhui Province are mostly descendants of Chang Yuchun and his own people. Hui people with Chang surname are mainly distributed in Beijing, Shandong and Jiangsu. Ancestor: Uncle Kang. Kang Shu is Zhou Wuwang's younger brother. Because his fief was Kangyi, he was called Kang Shufeng, also called Kang Shu. At the beginning of the Zhou Dynasty, Wu Geng, the son of Shang and Zhou Dynasties, launched a rebellion and was later suppressed. Therefore, before Kang Shu was sealed, the surrounding area of Shangdu and the seven tribes of Yin people established the State of Wei (now in the Yellow River valley of Henan and Hebei) and Du Song (now in Qixian County of Henan), and then moved to Diqiu (now in Puyang, Henan). At that time, the governors had a enfeoffment system, and Kang Shu had a son who was enfeoffed in a fief in Weiguochang (now southeast of Tengzhou City, Shandong Province). Qin unified the world, and the country was ruined. Later, some people took the city as their surname, called Chang's, and respected Uncle Kang as their ancestor.
