The story
The date was Tango no Sekku, the boys' festival, one of the five seasonal festivals, on which samurai families set out armour and flew banners. After the war it was made a day for all children and their mothers by law, and kept the boys' emblems.
The carp is the emblem because of a Chinese story in which a carp swims up a waterfall and becomes a dragon: a child who keeps going against the current will make something of themselves.
Korea's Eorininal was founded in the 1920s by the writer Bang Jeong-hwan, who coined the word eorini for a child as a person in their own right, and landed on 5 May as a spring day when the whole family could be out of doors.
