《龟旨歌》是韩国历史上仅存的最早的数首诗歌之一,由于它意义不明,难以解读,近百年来出现了各种怪异的看法。笔者认为,《龟旨歌》是一首龟卜歌,诗歌中的所有因素都是源于龟卜,而且与汉代的龟卜方法基本吻合。“喫”字是“契”字之误刊,“契”也是龟卜的主要用语。《三国遗事》最初的刊本就误刊了“喫”字,此后所有刊本皆延续了这一误刊之字,这是各种异说纷出的原因之一。 “Turtle Purpose Song” is one of the earliest few first poems in Korean history, because of its unknown meaning, difficult to interpret, appeared in the past century a variety of weird views. The author believes that “turtle song” is a turtle song, all the elements in poetry are derived from Turtle Bu, but also with the Han Dynasty Turtle Bu basically consistent. The word “eat” is the misunderstanding of the word “deed”, and “deed” is also the main term of turtle. The original edition of the Three Kingdoms was mistakenly published in the essay “Eat”, and thereafter all journals have continued the word of misinformation, which is one of the reasons for various myths.
