Gěnghé (Celestial Lance, 梗河), is a Chinese constellation Consists of 3 stars north of the Dajiao (Great Horn, 大角, α Boo, Arcturus (Ἀρκτοῦρος)) in Bootes.
Concordance, Etymology, History
It may be because the three stars lie almost along a single straight line that Genghe was regarded as the long spear or lance, located north of the Dizuo(Imperial Seat, 帝座/帝席) of Dajiao (Great Horn, 大角). It was said to govern the emperor’s military edge (or martial authority), and also to preside over foreign (Hu) troops and matters of mourning.
Identification of stars
The identification of Genghe is very consistent, corresponding to the three stars ε, σ, and ρ in the constellation Bootes.

In the Huangyou (皇祐) Star Catalog of the Northern Song Dynasty (1052), the determinative star for Genghe is the southeast star ε Boo. However, in the earlier Shishi (石氏) Star Catalog and Jingyou (景祐) Star Catalog (1034), it is the northwest star ρ Boo.
