In this festival,
dolls are loaded up in boats and sent out to sea with the wish
that they take impurities and evil spirts out of the girls and
keep them at bay.
Originally, people
rubbed drawings of people on themselves and let them float away
in a river. Impurities were thought to have been transferred to
the drawing and the person would be free of evil. This evolved
into the making of paper dolls and sending them downriver. Now
the ritual is very involved with hundreds of elaborate dolls and
a rich ceremony.
