Family Name: The surname 奥 (Ào) has multiple origins. One theory suggests it derived from ancient ethnic groups such as the Xianbei or Khitan, who later adopted Chinese surnames. Another theory traces it to the place name 'Ao Di' in modern-day Shanxi, where residents took the location as their surname. Additionally, some families adopted the surname 奥 due to name changes for reasons like avoiding taboo or conflict.
