Chroniken der Drei Reiche
The 3rd-century historical text "Records of the Three Kingdoms" did not state the name of the Qiao sisters' father, who was simply referred to as "Qiao Gong" (橋公; literally "Elder Qiao"). Historically, Qiao Xuan died in 183 while the Qiao sisters married Sun Ce and Zhou Yu in 200, so it was not possible that Qiao Xuan was still living when the marriages took place. Therefore, it is highly unlikely that Qiao Xuan was the "Qiao Gong" mentioned in the "Records of the Three Kingdoms".
