The name of the country is also called “Hongguo” and “Qiongguo”, and the sound of “gāng” is pronounced in ancient times. This country takes “Red Bird” as its totem. According to “Yuan He’s Surname Code” and “Tong Zhi-Clan Brief”, Jiang Yuanzhong, with the name of En Cheng and the character Zhong, is the third son of Bo Yi, and Emperor Xia Qi is Dali (the official in charge of criminal names). He was sealed in Jiangyi in 1101 BC and established Jiangguo. The state capital of Jiang in Zhou Dynasty is located in the southeast of Zhengyang County, Henan Province, one kilometer north of Huaishui River. There is an old city of Jiangguo, with a rectangular plane area of about 175,000 square meters, dating from the Eastern Zhou Dynasty to the Han Dynasty. During the 35 years in the middle of the Spring and Autumn Period, the state of Jiang attached itself to the state of Chu in order to revive. After that, he cut Chu with Qi and Song. In the Eastern Zhou Dynasty, Jiang State was located between the big countries such as Chu, Qi and Song, and was often invaded by the Huaihe River flood, so it never developed. In 624 BC, King Chu Mu sent troops to cut down the river, and Jin sent troops to clear the river. The following year, Chu sent troops again, and Jiang Guo was weak and the reinforcements were not followed, which was eventually destroyed by Chu. Jiang Guojun Zhen led the people to flee. To commemorate the old country, the Chinese took Jiang as their surname. From Jiang Ji’s being sealed to Jiang Zhenguo’s death and changing his surname, Jiang Guo coexisted with seventeen emperors for nearly 500 years. After the country was destroyed by Chu, some Jiangren were moved by Chu Guoqiang to Jiangting in the inland of Chu, and now they become subjects of Chu in Jiangbei, south of Jiangling, Hubei Province. Some Jiangren fled north into Chen Guo, now Huaiyang area of Henan Province, and then scattered around from Huaiyang as the center, and one of them moved northeast to Qilu. Later, the descendants took the country name as their surname and called Jiang.
