There is a Korean story whose title is 콩쥐 팥쥐
Even though I do not know the ending of the story, it is very similar to 신데델라 Sindedella : 팥쥐 is a daughter of step mother.
Question : What are meanings of 콩쥐, 팥쥐 ?
팥=adzuki bean=red bean=It is a bean of red color whose taste is sugary.
2) 콩쥐? a mouse eating beans ?
The reason that I think such is as follows : There is a similar word comparing to 콩쥐.
다람쥐 = squirrel. 다람 = 다름질 = 담박질 = 달리기 = run ? That is, 다람쥐 is a running mouse ?
