According to historical records, Jiang's surname is a descendant of Emperor Yan, and it is one of the oldest surnames in China.
Shuowen said, "Shennong lives in Jiang Shui because he thinks he is a surname." The legendary Emperor Yan, namely Shennong, is said to be one of the most ancient "san huang" in the history of China. Yan Di was born in Jiang Shui (now Qishan County, Shaanxi Province), so he took Jiang as his surname. Therefore, the birthplace of Emperor Yan is also the birthplace of Chiang Kai-shek.
Jiang: It's from Shennong. Emperor Yan Shennong lived in Jiang Shui, a tributary of the Weihe River, so he took the name of the river as his surname. In the Spring and Autumn Period, Qi, Shen, Lu, Xu and other feudal countries were all named Jiang. [Edit this paragraph] Migration distribution <; /B> Later, in the course of history, due to various reasons, many descendants of Emperor Yan have changed to other surnames. On the occasion of Yu and Xia, Bo Yi, the grandson of Yan Emperor and the ancestor of Siyue Mountain, was sealed in Lu (now Nanyang County, Henan Province) for his meritorious service in assisting Yu in water control, and the Lu State was established, and the ancestral surname Jiang was given again to continue the incense of Yan Emperor.
Qi State, one of the five tyrants in the Spring and Autumn Period, was founded by Lu Shang of Lu State. Historical records say: "Lu Shang, surnamed Jiang Mingya, has made meritorious deeds in the four mountains, and his descendants follow the surname." Lu Shang, a descendant of Shennong's Jiang Taigong Jiang Ziya, was named Lu Shang because of his meritorious service in governing the four mountains. His descendants inherited the monarch of the State of Qi, who lived for the 29th time. Later, the State of Qi was destroyed by Tian He during the Warring States Period, and the State of Qi became Tian's regime. Its descendants lived in different places and took Jiang as their surname. In this way, the surname Jiang, who moved to various places, continued to multiply and develop, and by the Han Dynasty, it had developed into a big family.
According to historical records, as early as the Spring and Autumn Period, Xirong also had a surname of Jiang, so it was called Jiang Rong, originally in Guazhou (now Dunhuang West, Gansu Province), and then gradually moved eastward. In about 638 BC, its leader moved to southern Shanxi, belonging to the State of Jin. Before the Western Han Dynasty, the Jiangs, who lived in present-day Shandong and Henan provinces, had developed into a Kanto clan (the area east of Hanguguan in Lingbao County, Henan Province). At the beginning of the Western Han Dynasty, in order to enrich the population of Guanzhong, Jiang moved from Kanto to Guanzhong, and this later generation lived in Tianshui (now Gansu), so the people took "Tianshui" as the county name. By the Han Dynasty, Jiang's family had migrated to Jiangsu and Sichuan. However, until the Tang Dynasty, Tianshui was still the development and reproduction center of Jiang's family. During the Tang and Song Dynasties, Jiang's family was also distributed in Hebei, Henan, Zhejiang, Jiangxi, Anhui, Shandong and Qiongshan, Guangdong. In the Ming and Qing dynasties, some of the Chiang family lived in Shanxi, Shaanxi, Hunan, Guizhou, Hubei and other places. According to Jiang's genealogy, during the Hongwu period of the Ming Dynasty, a Jiang Shiliang moved to Hongdou Village, Longxi County, Zhangzhou, Fujian Province, and made a fortune here. Its descendants multiplied, and another branch moved to Yandun Township, Lufeng, Guangdong Province, and continued to prosper and develop. Later, Jiang Shiliang 1 1 Shi Sun moved to Taiwan Province from the mainland during the Qianlong period of Qing Dynasty. Since then, people from Fujian and Guangdong have moved to Taiwan Province, and some have spread overseas.
