春秋
It is unclear when Sun Guangxian was born. Both the "History of Song" and the "Spring and Autumn Annals of the Ten Kingdoms" indicated that he was from Guiping (貴平, in modern Meishan, Sichuan) — although the "Spring and Autumn Annals of the Ten Kingdoms" acknowledged that one of Sun's own works, the "Beimeng Suoyan" (), stated that he was from Fuchun (富春, in modern Hangzhou, Zhejiang).
