Chinese name

In Chinese language, 紫微右垣, meaning Right Wall of Purple Forbidden Enclosure, refers to an asterism consisting of 43 Camelopardalis, α Draconis, κ Draconis, λ Draconis, 24 Ursae Majoris, α Camelopardalis and BK Camelopardalis. Consequently, 43 Camelopardalis itself is known as 紫微右垣五, representing 上衛, meaning First Imperial Guard. 上衛 is westernized into Shang Wei by R.H. Allen, the meaning is "Higher Guard", but it is not clearly designated. The identification of Shangwei has varied across historical sources, and the IAU [Working Group on Star Names] has adopted it as a name for HD 42818, based on an older identification.
