the korean equivalent hansik (hangul: 한식), takes place on the 105th day after "dongzhi", which translates to april 5 in the gregorian calendar. it is a day to welcome the warm weather thawing the frozen lands. on this day, rites to worship ancestors are observed early in the morning, and the family visits their ancestors' tombs to tidy up. the custom of eating cold food on the day has, however, disappeared. since this day coincides with arbor day, public cemeteries are crowded with visitors planting trees around the tombs of their ancestors.
