The stars that correspond to Eridanus cannot be fully seen from China. In Chinese astronomy, the northern part is located within the White Tiger of the West (西方白虎, "Xī Fāng Bái Hǔ"). The unseen southern part was classified among the Southern Asterisms (近南極星區, "Jìnnánjíxīngōu") by Xu Guangqi, based on knowledge of western star charts.
