### Migration and Distribution (No information available) The surname Huan is not ranked among the top 100 surnames on the Chinese mainland or in Taiwan. The Huan clan ranks 407th in the Song edition of the "Hundred Family Surnames", and its place of origin is the Qiao Commandery (present-day Bozhou County, Anhui Province) during the Han Dynasty. There are four origins of the Huan clan: 1. It comes from the Jiang surname. According to the "General Annals of the Clans and Surnames in the Comprehensive Gazetteer", during the Spring and Autumn period, Prince Xiaobai, the younger brother of Duke Xiang of Qi, fled to the State of Ju. After Duke Xiang was killed, Xiaobai returned to the State of Qi to ascend the throne. He appointed Guan Zhong to carry out reforms and became the first of the Five Hegemons in the Spring and Autumn period. After his death, he was posthumously titled "Huan", known as Duke Huan of Qi. His collateral descendants took the posthumous title as their surname and were called the Huan clan. One branch descends from Duke Huan of Qi. 2. It comes from the Zi surname. Xiang Gui, a collateral descendant, took his grandfather's posthumous title as his surname and was called Huan Tui. 3. It is simplified from the "Huan Hou" clan. During the Zhou Dynasty, there were Marquis Huan in the States of Jin (with the Ji surname), Qi (with the Si surname), and Cao. Their descendants had the "Huan Hou" clan, which was later simplified to Huan. 4. It is from the Xianbei ethnic group who came to China during the Northern and Southern Dynasties. As recorded in the "General Annals of the Clans and Surnames in the Comprehensive Gazetteer", the descendants of Duke Huan of Qi took the posthumous title of Duke Huan as their surname. The descendants of Duke Huan of Song also called themselves the Huan clan. In addition, the Wuhuan clan of the Later Wei also changed their surname to Huan. Moreover, both the "Yuanhe Compilation of Surnames" and the "Book of Wei - Records of Official Titles and Clans" have texts verifying the origin of the Huan clan. It can be seen that among the ancient Huan clan, there are descendants of Jiang Taigong from Shandong, descendants of King Tang of Shang originating from Henan, and also a small number of descendants from the Xianbei ethnic group. The prominent family is based in the Qiao Commandery (present-day Bozhou County, Anhui Province).

Migration and Distribution The surname "Huan" is not listed among the top 100 surnames in the Chinese mainland and Taiwan. The surname "Huan" originated from the concept of being an official. Initially, it referred to holding an official position. Therefore, some people who aspired to be officials took "Huan" as their surname. According to the "Five Books on Surnames" in the Qing Dynasty, the surname "Huan" "should be derived from the meaning of being an official, not from eunuchs." However, in the old days, some people thought it was from eunuchs. Eunuchs are those who were castrated and served the royal family and concubines in the deep palace. Because they were close to the royal family, they sometimes held great power. So, some people also took this eunuch - related origin as their surname. Development and Evolution: Later, "Huan" came to refer to those castrated people who served the royal family and concubines in the deep palace. Although there were several influential eunuchs in history (such as Gao Lishi in the Tang Dynasty) who could hold great power because of their close proximity to the royal family, and some people took the surname based on these eunuchs, since eunuchs were generally discriminated against, many descendants of the "Huan" surname changed to other surnames, and the number of people with the surname "Huan" became fewer and fewer. Nowadays, some families with the surname "Huan" can only be found in Zunyi County, Guizhou Province, and Danyang County, Jiangsu Province. The prominent families of the "Huan" surname are located in Dongyang (now Jinhua, Zhejiang Province) and Zhongshan (Ding County, Hebei Province).
