Evidence suggests that during the Han Dynasty the military and civil officials all took a day off on the summer solstice, returning home to bathe and to gather together with their families for a while. There is also a saying, "Wonton at the winter solstice, noodles at the summer solstice." After half a year of eating steamed sorghum bread they were able to enjoy a big feast of noodles.
