高句丽始祖传说中的“河伯女”内容是高句丽人为增加其始祖传说的神秘色彩而增添的,主要是为了加强其始祖朱蒙驾驭水族的能力,弥补其“鱼鳖架桥”传说的不足。其增添的内容也与内地相类传说息息相关。王氏高丽建立后,许多文人加入到改造海东传说的行列,高句丽河伯女传说得以继续发展,内容不断增强,形象日益丰满。 In the legend of Goguryeo, the content of “River Boy Female” is added by the Goguryeo artificially increasing the mystery of the ancestor’s legend, mainly to strengthen the ability of its ancestor, Zhu Meng, to master the aquarium and make up for its “fish and turtle bridges” legend Insufficient. Its added content is also closely related to the legend of the Mainland. After the establishment of Wang Gaoli, many scholars joined the ranks of the transformation of Haidong legends, and the legend of the Koguryo River and Bo and her daughter continued to develop. The content was continuously enhanced and the image was increasingly plump.
