By comparing with the folk tale, , this study examined the reason why the latter was limited to the legend of some areas, while the former was transmitted across the nation with the similar narrative structure. For this, we attempted to analyze the meaning of all motifs which has, getting out of the previous studies which were to understand this legend only with one motif(taboo).
As a result of comparison, it was found they were different in many motifs although both folk tales have something in common in that they are the \'sinking pond legend\'(which is the legend about the origin of a pond) that their villages turn into ponds as the meaning to punish evil of characters who do nothing but doing evil conduct. In addition, it was identified that theses differences have a great effect on transmission power.
First, it can be seen that the motif of \'taboo\' does not appear in the folk tale of . By this, an old woman bestows endlessly broad good by sharing ‘a prophecy from the God’ with everyone. However, any village people do not believe her words, and in the end, only she survives. As mentioned above, she might feel the pleasure to join the world of ‘God’ but did not give an deep impression on people(narrator of the folk tale). On the contrary, in a taboo motif \'not to look back\' appears. This was the final test for a daughter-in-law to enter the world of God\' abandoning \'her family including her father-in-law, husband and children\'. However, in the long run, the daughter-in-law gives up joining the world of \'God\' alone feeling sorry to her family and \'turning her head\' to become \'a stone\'. However, this gave a deep impression on people and she was worshiped as ‘a tutelary deity’(the god of Sonang), and winning great literary sympathy, it could be transmitted across the nation.
Second, both folk tales are different also in the motif of characters. While in , ‘family relations of a father-in-law and a daughter-in-law\' are set up, \'neighbor relations of a grandmother and village young people\' are set up in the folk tale of . This makes differences whether they are in symbiosis relationships to share ‘fortune and misfortune’ or they are in the relationships to share only ‘happiness\'. It is clear that our nation who valued the shelter of \'family\' in Confucian society considered human relations of the former as more attractive motif.
Third, there are differences depending on whether transposition occurs or does not occur in the heroes or heroines\' hierarchy. Although the daughter-in-law did not reach it at this point of time, the hope was preserved to join the new world someday by completely changing(transposition) the existing world(the father-in-law-upper side) and the new world(the daughter-in-law-lower side)and in . On the contrary, no hope can be found to remove darkness of the reality as there\'s no change in the hierarchy of characters from the beginning to the end in the folk tale of . Namely, for this reason, in which the hope remains to join the new world could be handed down orally nationwide building still greater literary sympathy than the flak tale, .
