Old documents read that the people in the period of Koguryo (277 BC-AD 668), the first feudal state of Korea, had a bath in a stream east of the village and enjoyed a feast of dishes.
Typical dishes on the day include congee with fish, noodles, rice cake dumplings, fermented rice cake and pancake.
Its name is originated from the fact that noodles made of the flour of new wheat are eaten on the 15th day of the sixth month by the lunar calendar.
When new wheat is harvested around mid-June by the lunar calendar, it is ground into flour to make noodles.
Sliced or chopped noodles are served in soybean soup. Sometimes, perilla seeds are roasted and added to soybean soup, which makes noodles tastier.
