1, from Jiang's surname
Take the city name as the surname. According to the New Tang Book, Prime Minister's Spectrum Table, Yuan He's Compilation and other materials, Ji Zi, the eldest son of Jun Ding of the State of Qi in the Western Zhou Dynasty, was a descendant of Shen Nong's family, who once ate in Zhangqiu City, Shandong Province, and later took Yi as his surname, and was named Cui Shi, Shandong Province. According to various ancient records, Cui Shi came from Jiang. Cui's surname came from Qi State in the Western Zhou Dynasty, with a history of nearly 3,000 years. Once a famous Shandong family, China had a long surname. Qi was one of the important vassal states in the early Western Zhou Dynasty, with its capital in Linzi (present-day Zibo) and the founding monarch being Lu Shang. Lu Shang was originally surnamed Jiang, and was sealed in Lu (now Nanyang, Henan Province) because of his ancestors, and later took Lu Shang as his surname. Ding Gongyi, the son of Lu Shang, is the second generation monarch of Qi. His eldest son, Ji Zi, should have succeeded to the throne, but he gave way to his younger brother, Uncle B, who lives in Cui Yi (now the northwest of Zhangqiu) and lives here. Later, the city was named Cui Shi.
And this Ding, according to legend, is the son of Jiang Ziya. Therefore, Cui Shi China people are the direct descendants of Jiang Taigong, and they are the descendants of the ancient Yandi Shennong. Their surnames have a history of more than three thousand years.
