Naming
In Chinese caused by adaptation of the European southern hemisphere constellations into the Chinese system, 夾白 (Jiá Bái), meaning White Patches Attached, refers to an asterism consisting of θ Doradus and α Reticuli. Consequently, θ Doradus itself is known as 夾白一 (Jiá Bái yī, English: the First Star of White Patches Attached.)
