Did Xiao Qiao marry Cao Cao?

Xiao Qiao was originally Zhou Yu's wife. In order to avenge Guan Yu, Liu Bei was defeated by Sun Quan and died in Baidicheng. After being defeated by Sun Quan, Guan Yu fled to Maicheng and was killed by General Wu Dong. Cao Cao has been a soldier all his life, and his work is tense and tired. He may have suffered from cerebrovascular disease, migraine or benign tumor lurking in his brain very early. History is not clear about his illness. Therefore, the death of Cao Cao is still a mystery.
