Toghon Temür
Toghon Temür was born to Kuśala, known as Khutughtu Khan or Emperor Mingzong, when he was in exile in Central Asia. Toghon Temür's mother was Mailaiti, descendant of Arslan Khan, the chief of the Karluks. According to a folk legend, the former Chinese Southern Song Emperor Gong of Song, Zhao Xian, had an affair with Yuan Empress Mailaiti. Zhao Xian allegedly fathered Yuan Toghon Temür with Mailaiti as a bastard child. The Mongols circulated a similar story about the Yongle Emperor.
