The surname is the ancestor Jiang Boling. Zhou Gongdan's third son, Zhou Wuwang Ji Fa, founded the Zhou Dynasty after destroying the dissolute Shang Zhouwang, and died shortly after his rule. Zhou Chengwang inherited him. Because he was a young king, he was regent of Zhou Gongdan. Zhou Gongdan helped him quell the rebellion of Wu Geng, the son of Shang Zhouwang, determined the patriarchal clan system, established laws and regulations, and constantly enfeoffed governors with the same surname. Among them, the third son Buring was sealed in Chiang Kai-shek, known as Jiang Bo in history. In 6 17 BC, Jiang Guo was destroyed by Chu, and later generations took the country name as their surname, and respected Jiang Boling as the ancestor of Jiang.
Breeding and moving to Henan is the original birthplace of Jiang's surname. After Chu destroyed Jiang, most of Jiang's surnames emigrated, except for some who stayed in Henan. During the Qin and Han Dynasties, Jiang moved to Shaanxi in the west and Shandong in the east. Among them, the ginger in Boxing and Shouguang, Shandong Province is the most prosperous, so the ginger generation has the custom of taking "Le 'an" as the name of the hall. Jiang's surname moved south earlier than other surnames, which began in the Han Dynasty. During the Jianwu period of the Eastern Han Dynasty, Hou Jiang was slandered, and his nine sons took refuge everywhere. After Emperor Guangwu woke up, all nine sons were sealed, namely Hou Ying, Hui Ji Hou Zheng, Su Lin Hou Zhe, Hu Lin Hou Yao, Pu Ting Hou Xun and Linjiang (now Zhongxian County, Sichuan Province) Hou Chuan. It can be seen that since Jiang Heng, most of his descendants have scattered in Jiangsu, Jiangxi, Zhejiang, Sichuan, Hubei, Hunan and other places in the south of China, becoming the local ancestor of Kaiji. This greatly increases the range of ginger's activities. At the end of the Eastern Han Dynasty, a branch moved from Henan to Donglai County, Shandong Province, and Jiang Ji of Cao Wei was its descendant during the Three Kingdoms period. During this period, Jiang Xiu (the tenth grandson of Jiang Yi, a famous minister in the Western Han Dynasty) moved from Le 'an to yi county (now Yixing, Jiangsu), and his descendants moved to the Three Mausoleums in Fenghua, Zhejiang. According to research, there are no two Chiang Kai-shek. China, whose surname is Chiang Kai-shek, originally came from the same family. After the Han Dynasty, Jiang's surname was mostly from Yixing, Jiangsu, and his ancestor was Hou Jiangcheng of Hanting. Later, most of China's Jiang surnames came from Yixing. At the beginning of the Tang Dynasty, he opened in Fujian, accompanied by Jiang. During this period, a man surnamed Jiang from Tiantai, Zhejiang moved to Fenghua, Zhejiang. During the Five Dynasties, Jiang Xian, a descendant of Jiang Yi, served as a salt supervisor in Siming and lived in Cailian Bridge in Ningbo. His descendants became famous scholars in Ningbo. After the Song Dynasty, the surname Jiang in Fujian, Guangdong and other places began to flourish. In the Yuan Dynasty, Shi (a descendant of Dr. Jiang Guanglu) moved to Niaoxiao Township (now Xikou Town) in Wuling, Fenghua, and was the ancestor of Chiang Kai-shek. During the Ming and Qing Dynasties, a surname from Fujian, Guangdong, Jiangxi and other places emigrated overseas. 1949, Chiang Kai-shek was defeated in Taiwan Province Province, and a large number of people surnamed Jiang followed. Today, Chiang's family has spread all over the world, especially in Sichuan, Jiangsu, Hunan, Zhejiang and other provinces. The population of Chiang's family accounts for about 60% of the Han population in China.
