曹丕
After Cao Cao died in early 220, his vassal king title – "King of Wei" () – was inherited by Cao Pi. Later that year, Cao Pi forced Emperor Xian, whom he paid nominal allegiance to, to abdicate in his favour, effectively ending the Han dynasty. Cao Pi became the emperor and established the state of Cao Wei, which marked the beginning of the Three Kingdoms period. The dethroned Emperor Xian was reduced to the status of a duke – the Duke of Shanyang (). The former emperor presented his two daughters to Cao Pi to be his concubines. Cao Pi began to favour his other concubines, especially Guo Nüwang. When Lady Zhen realised that Cao Pi favoured her less, she started complaining. Cao Pi was furious when he heard about it. On 4 August 221, he sent an emissary to Ye (in present-day Handan, Hebei) to execute Lady Zhen by forcing her to take her own life. Lady Zhen was buried in Ye on 20 March 227.
