Princess Changshan is the formal title of a daughter of the regent of the state of Cao Wei, Sima Zhao.
Princess Changshan is recorded as having been blind in both eyes,[1] though it is unclear from the texts whether this was congenital or developed over time.
She was the sister of Emperor Wu of Jin and the primary wife of the official Wang Ji (王濟), who is recorded as having greatly favoured her.
[1] He demoted Wang for lacking in filial piety, who then moved to live north of Mt Mang (Chinese: 邙山) near Luoyang, Hebei.
While the eldest son inherited the rank of Wang's father, the second son Wang Yu (Chinese: 王聿) inherited Princess Changshan's rank and received the title Marquis Minyang (Chinese: 敏陽候).
