Family Name: The surname 郭 originates from the character meaning 'outer city wall.' One theory suggests it derives from the State of Guo during the Xia Dynasty, where the descendants of the state's rulers adopted the surname, later changing from 虢 to 郭 due to phonetic similarity. Another theory links it to the Zhou Dynasty, where descendants of Duke Guo, a brother of King Wen of Zhou, took the surname 郭 after their state.
