Tracing back to the source, the surname often comes from the surname Jiang. According to "Yi Tong Customs" and "Biography of Chenliu Customs", Chang's surname originated from the State of Qi in the Spring and Autumn Period, and later it was Gong's surname.

Ancestor Lv Wang. That is to say, Jiang Shang, who is pronounced as Ziya, disappeared in Weibin first, and Zhou Wenwang met him while hunting in Weihe River. He said, "I have been looking forward to my son for a long time", so he was named King Taigong, commonly known as Jiang Taigong. In the process of assisting Wen Wang and destroying Shang Dynasty, Lv Wang played the following roles: 1. Formulating the strategy of "respecting people" to paralyze Shang and Zhou Dynasties; Second, take the steps of netting the whole country and eliminating the wings of Shang Dynasty; Third, boost morale and be strict in discipline; Fourth, the battle of Makino personally ordered the assault. After assisting King Wu to complete the great cause of destroying business, Lv Wang was listed as the first letter, which was sealed in Qi, with Yingqiu as its capital (now east of Zibo, Shandong) and became the ancestor of Qi.

Things have changed, and gradually formed a large settlement in Henan County, north of Luoshui, and Wei County between Hebei, Shandong and Henan. Its population is prosperous. During the Jin and Southern and Northern Dynasties, the Central Plains was in turmoil and smoke filled everywhere. Like other gentry in the Central Plains, Zhang escaped from troubled times and entered southern provinces such as Anhui, Jiangsu and Zhejiang. During the Sui and Tang Dynasties, there were still Chang surnames in Henan county, but Linzhang, where Wei Jun ruled, was burned down several times in the war, so Chang surnames had to be scattered everywhere. A Shanxi province that moved into mountains and rivers inside and outside was registered in Hedong County in the south of Shanxi. In the middle Tang Dynasty, Chang Dang, who was famous for a poem with the same name as Wang Zhihuan, was from Hedong County. This poem and Wang's poem are both good poems with mixed scenes. The poem says, "On the birds, high above." The Southern Song Dynasty was partial to the south of the Yangtze River. After Mongolian fighters trampled on the south of the Yangtze River at the end of the Song Dynasty, the people surnamed Chang could not bear the pain of war, or made a living, or fled, or officials gradually dispersed in Hubei, Hunan, Jiangxi, Fujian, Sichuan and other provinces. At the beginning of the Ming Dynasty, Shanxi Chang moved to Beijing, Shaanxi, Hebei, Henan and other places. During the Ming and Qing Dynasties, the mainstream of Chang surname reproduction was still in the north, and then there were various natural migration movements such as going west and crossing Kanto, and Chang surname gradually distributed in northwest, northeast and south China.

Today, Chang is widely distributed in China, especially in Shanxi and Henan. ?
