The so-called "soup cake" in this historical fact is today's hot noodle soup, that is, today's Beijing's "pulling a piece."
In Shandong, Hebei and Henan, people not only slice bread into pieces to make noodle soup, but also cut it into prismatic slices the size of a finger belly with a knife and cook it in mung bean soup. It is called "face chess piece" or "mung bean chess piece".
At that time, the soup cake was the precedent of noodles and noodle soup in later generations. Eating noodles during the summer solstice is a kick of nature, which is also related to the seasonal weather at that time.
Chinese people's proverb Day: "See the wheat flowers in three days." Around the summer solstice, it is the season when new wheat is in season. People first have a material basis for eating noodles. And writing noodles is relatively simple. It's convenient to cook and eat.
In ancient times, people usually held sacrificial ceremonies on the summer solstice, praying for heaven to bless the disaster and save the year. "Zhou Li Chun Guan" contains: "With the arrival of summer, to local things."
Sacrificing to God in the Summer Solstice of the Zhou Dynasty means clearing away plagues, famine years and death from hunger. At this time, new folk wheat came out, and people worshipped God with pasta. The custom of eating pasta on the summer solstice has also spread to this day.
After catching cold in summer, symptoms such as stuffy nose, aversion to cold, headache and heavy body often appear. Cooking a bowl of hot noodles, adding some scallion and pepper, and tasting it while it is hot, has certain auxiliary therapeutic effect.
Because the new wheat on the summer solstice has appeared, eating noodles on the summer solstice also means tasting new things. From the point of view of nutrition, around the summer solstice is the time when wheat is harvested and new flour is on the market, and the nutrients in fresh flour are high.
In the past, people ate more noodles at this time, on the one hand, to celebrate the bumper harvest, on the other hand, they could also draw rich nutrients from noodles made of new flour with good taste.
