In 2019, Hu was the fifteenth most common surname in Mainland China. Some other, less common surnames pronounced Hu include 瓠, 護, 戶, 扈, 虎, 呼, 忽, 斛 and 壶. In Cantonese, “胡” is also pronounced as "Wu" or "Woo" or "Ow". Meaning In Classical Chinese, hú 胡 meant: "dewlap; wattle" and was a variant Chinese character for "how; why; what" (he 何), "long-lasting; far-reaching" (xia 遐), "part of a dagger-axe", hu- in "butterfly" (hudie 蝴蝶), or possibly "Northern Barbarians". History According to tradition, the Hu (胡) surname has several historical origins. First, Hu could derive from the family of Duke Hu of Chen. King Wu of Zhou (r. 1046-043 BCE) enfeoffed his son-in-law Gui Man 媯滿 (supposedly a descendant of the legendary sage king Emperor Shun) with the state of Chen (in modern Henan Province). His posthumous name was Duke Hu, and some of his descendants adopted Hu as their surname. Second, Hu could derive from two Zhou vassal states named Hu 胡, one located near Luohe (Henan Province) or another near Fuyang (Anhui Province). Third, Hu could derive from non-Chinese people adopting it as their surname. For example, in the 496 Change of Xianbei names to Han names, Hegu/Gegu 紇骨 was changed to Hu 胡. Fourth, Hu could derive from the clan name of the ancient Tiele people within the Xiongnu confederation. Non-Chinese peoples and ethnic minorities in China sometimes took the Chinese exonym for their ethnic group as their surname. The best example is Hu 胡, which was anciently used to refer to "barbarian" groups on the northern and western frontiers of China. Hu (胡) was used for various northern and western peoples of non-Chinese stock. It was commonly used for people of Persian, Sogdian, Turkic, Xianbi, Indian and Kushan origin and, occasionally, for the Xiongnu (probably because of their connections with the Tonghu or Eastern Hu – a separate tribe conquered by the Xiongnu). Two historically significant Hu names are this Donghu 東胡 (literally "Eastern Barbarians") "ancient Mongolian nomadic group" and the Wu Hu 五胡 ("Five Barbarians") "five nomadic tribes involved in the Wu Hu uprising" (304-316 CE) against the Jin Dynasty.
