Cao is a Vietnamese surname. The name is transliterated as Gao in Chinese and Go in Korean. Unrelated, it is also the Chinese surname Cao which is transliterated as Tào in Vietnamese.
Cao (/ˈtsaʊ/) is the pinyin romanization of the Chinese surname 曹 (Cáo).
It was listed 26th among the Song-era Hundred Family Surnames.
Cao is romanized as Ts'ao in Wade-Giles, although the needed apostrophe is often omitted in practice. It is romanized Cho, Cou, Tso, and Chaw in Cantonese; Chou, Chô, and Chháu in Min Nan; Chau, Chow in Teochew; and Tháu in Gan.
The Vietnamese surname based on it is now written Tào; the Korean surname is now written 조 and romanized as Jo or Cho; and the Japanese surname which still employs the same Kanji is romanized Sō.
At last count, Cao was the 30th-most-common surname in mainland China and the 58th-most-common surname on Taiwan.
In the United States, the romanization Cao is a fairly common surname, ranked 7,425th during the 1990 census but 2,986th during the year 2000 census. It is one of the few Chinese surnames whose pinyin transcription is already more common than other variants. The Wade transcription Tsao was only ranked 16,306th during the 1990 census and 12,580th during the year 2000 one. The Cantonese transcription is actually becoming less common, falling from 7,638th place to 9,925th. The Korean name Cho is more common still than Cao, befitting its frequency in Korea itself, where it makes up about 2% of the South Korean population: see Cho (Korean name).
The State of Cao (simplified Chinese: 曹国; traditional Chinese: 曹國; pinyin: Cáoguó) was a vassal state in China during the Zhou Dynasty (1046–221 BC). The state was founded sometime in the 11th century BC by Caoshu Zhenduo (d. 1053 BC) (曹叔振鐸), son of King Wen of Zhou and the younger brother of King Wu of Zhou. With its capital at Taoqiu (陶丘), the State of Cao covered roughly the area of modern-day Dingtao County, Shandong Province. It was located on the flat country of the North China Plain about 50 miles east of the point where the current course of the Yellow River changes from east to north-east. To the northwest was Wey, to the northeast Lu and to the southeast Song.
As a result of the Cao’s relative weakness, later generations wrote few records on events concerning the state's history. The only major event recorded in the Records of the Grand Historian during the Western Zhou Dynasty (1046 – 770 BC) was in 826 BC when Count You of Cao was killed by his younger brother Count Dai of Cao.
Carlos Alberto Correia Fortes (born 20 October 1968 in Praia, Cape Verde), commonly known as Cao, is a Portuguese retired footballer who played as a defensive midfielder.
After unsuccessfully emerging through FC Porto's youth ranks, Cao went on to play 12 seasons in the two major levels of Portuguese football, representing Rio Ave FC (second division), F.C. Tirsense (first), Leça FC (first and second), S.C. Salgueiros (both levels), S.C. Campomaiorense (both) and F.C. Felgueiras (second).
He retired from professional football in 2003 with totals of 286 games and 11 goals, going on to spend the rest of his career in amateur football, which included a third spell with Leça. Subsequently, he worked as a graphic designer.
Cao was part of the Portuguese under-20 team that won the 1991 FIFA World Youth Championship, with the competition being held on home soil. In 2002 it was revealed that he had in fact been born in 1968, meaning he was crowned Youth World Champion at the age of 22.
