Editing Lelang Commandery (section)

===Cao Wei===
In 236, under the order of [[Cao Rui|Emperor Ming]] of [[Cao Wei]], [[Sima Yi]] [[Sima Yi's Liaodong campaign|crushed the Gongsun family]] and annexed Liaodong, Lelang and Daifang to Wei. Sima Yi did not encourage frontier settlers to continue their livelihoods in the Chinese northeast and instead ordered households who wished to return to coastal and central China to do so, evacuating the region of Chinese settlers. The [[Book of Jin|Jin Shu]] records the number of households in the Korean commanderies of Lelang and Daifeng as 8,600 households, less than a sixth of the figures given in the [[Book of the Later Han|Hou Han Shu]] for Lelang (which included Daifeng). Liaodong would be out of Chinese hands for centuries due to the lack of Chinese presence there as a result of the policies the Wei court adopted for the commanderies after the fall of the Gongsun family.<ref>Gardiner, K.H.J.
