独孤 is a historical compound surname (Dugu), famously borne by the Dugu family of the Northern and Southern Dynasties and by the character Dugu Qiubai in Louis Cha's wuxia novels. It also appears in classical literature with the meaning 'alone, lonely', derived from the individual characters 独 (alone) and 孤 (orphan/alone). In modern Chinese, this sense is archaic and mostly used in literary or poetic contexts.
