本文主要討論《山海經》中一足人、神、鳥、獸的相關形象與圖像。首先，《山海經》中有一臂國，接著著錄奇肱國，似乎不合常情，奇肱國或是奇股國之誤。《淮南子》中與一臂民並列的即是奇股民，而韓國流傳的一系列「天下圖」中，見到的也是奇股國，奇股國與一臂國相連，這些似都隱約透露，《山海經》中的奇股國被誤為奇肱國。其次，我們也在貴州的彝族中發現普遍流傳的獨腳神話，獨腳神話流傳在屬於古氐羌族群的彝族神話講述中，而獨腳野人被認為是帶領死後靈魂回到祖先懷抱的類似巫師角色。《山海經》中的各種一足形象與彝族神話的獨腳形象或者不是一種巧合。

This study investigates the images and graphs of one-foot humans, deities, birds or other animals in ”Shan Hai Jing”. ”Shan Hai Jing” first mentioned ”One Arm Country” and then curiously talked about ”Ji Gong Country” (Ji Gong also means ”One Arm” in Chinese). It makes one wonder the second country should be ”Ji Gu Country” (Ji Gu means ”One Foot” in Chinese) instead. ”Huai-Nan-Zi” listed ”One-Arm People” and ”Ji Gu People” together, while a series of ”World Map” passed down in Korea also put ”One-Arm People” and ”Ji Gu People” side by side. It seems to suggest that in ”Shan Hai Jing” ”Ji Gu Country” was mistaken for ”Ji Gong Conutry”. Moreover, ”One Foot” myth is also found widespread among Yi people in Guizhou. In the myth of Yi people, which belongs to Ancient Zhi-Qiang population, a one-foot wild man is thought as the character of a shaman who leads the souls of the dead back to the ancestors' embrace. It is probably not a coincidence that a Yi myth shares the same ”one foot” image with those cited in ”Shan Hai Jing”.
