Cao Rui

Cao Rui (died 13 June 233) was a prince in the state of Cao Wei in the Three Kingdoms period of China. He was a son of Cao Pi, the first emperor of Wei. His mother, whose family name was Pan (潘), was a concubine of Cao Pi holding the rank of shuyuan (淑媛; translated "Decent Concubine"). He was enfeoffed as the Prince of Yangping County (陽平縣王) in 226 after his half-brother, Cao Rui (曹叡; note the different character for Rui), succeeded their father as the emperor of Wei (with the posthumous title of "Emperor Ming of Wei"). In 232, his title was changed to Prince of Beihai (北海王). He died in 233 and had no offspring.
