The legend of winning surname is the descendant of the sage Boyi of Dayu. According to Yuan He Shi Bian written in the Tang Dynasty, "yuanshi county, following Sun Boyi, was sealed in the river and later destroyed by Chu, taking the country as his surname." Zhuan Xu, named after the ancient emperor, is one of the five emperors and is said to be the grandson of the Yellow Emperor. Boyi, the great-grandson of Zhuan Xu, was the leader of Dongyi tribe in Shun Dynasty. Because he helped Yu control water, Yu had to give way to him, and he took refuge in the north of Jishan (Jishan is located in the southeast of Dengfeng County, Henan Province).
The descendants of Boyi were sealed in Shang Dynasty or early Western Zhou Dynasty, and Jiang Guo was established. According to research, the capital of Gujiang Prefecture is located near Zhengyang County, Henan Province. During the Spring and Autumn Period, Jiang Guo was between the forces of Chu, Song and Qi, and was often manipulated by these great powers. In addition, the Huaihe River flooded the center of Jiang Guo, so Jiang Guo never became strong, and was finally destroyed by the State of Chu. After Jiang Guo's death, his descendants lived in various places, "taking the country as their surname", and Jiang's surname was passed down from generation to generation. It can be seen that the Chiang family is a descendant of Boyi, whose ancestor Boyi was yuanshi county, so the Chiang family originated in yuanshi county.
