Biography & Historical Record
Princess Qinghe (清河公主, 清河長公主, Thanh Hà công chúa; c. 190s–?) was the eldest daughter of late Eastern Han warlord and founder of Cao Wei, Cao Cao (曹操), born to his secondary consort Lady Liu (刘夫人). She was the full biological sister of Cao Cao’s eldest son, the heroic martyr Cao Ang (曹昂).
Initially sought in marriage by celebrated scholar Ding Yi, Cao Cao ultimately wed Princess Qinghe to Xiahou Mao (夏侯楙), the beloved son of Grand General Xiahou Dun, thereby reinforcing the supreme political and military alliance between the Cao and Xiahou lineages. When Cao Pi established the Wei dynasty, she was elevated to Eldest Princess of Qinghe (清河长公主). In later years, when Xiahou Mao kept numerous concubines while stationed in the western borderlands, Princess Qinghe boldly submitted a memorial to Emperor Ming Cao Rui accusing Mao of treason, demonstrating her independent and outspoken imperial authority.
