Why do you eat cold noodles on the summer solstice?

June 2 1 day of the lunar calendar is the summer solstice. I heard that I eat wonton in winter and noodles in summer. The winter solstice (Gregorian calendar1February 2 1 day or 22nd) is the beginning of September of the lunar calendar. The ancients thought it was a good day to celebrate the winter solstice, when the days were getting longer and longer and the yang was rising. Emperors in the Ming and Qing Dynasties had ceremonies to worship heaven, which was called "the suburb from winter to the sun". There was a ceremony in the palace where hundreds of officials congratulated the emperor. They also threw thorns at each other and congratulated each other, just like New Year's Day. However, people do not regard the winter solstice as a festival, but have some timely activities. In the Qing Dynasty, some flag-bearers invited their first cousins, close relatives and friends to sit on the ground in the courtyard at five o'clock from winter to Sunday, and sacrificed the "heaven and earth code" or memorial tablet with a low table, killing pigs to worship heaven. By the way, an "ancestor pole" (a flagpole two or three feet high, with a gourd-shaped top and a "Diao Dou" at the bottom, with a flag hanging under the bucket to represent ancestors) was offered. After the sacrifice, relatives and friends sit around and eat "white meat", which is called "Shenyu". Southerners who travel in Beijing will also hold banquets to worship their ancestors. At the same time, colleagues or close friends are invited to have dinner together. Yan customs are not important for winter festivals. Old Beijingers don't want this. On the day of winter solstice, a grand ceremony was held in all the streets of the capital. At the beginning of the Yuan Dynasty, the Taoist took a kiss and went to the table to celebrate the Buddha's birthday. According to Taoism, the Buddha in the early Yuan Dynasty symbolizes the first century when chaos and Taoism were not divided. Therefore, people have the custom of eating wonton. "Yanjing Years Old" says: "The shape of husband's wonton is like a chicken egg, which is quite similar to the chaos of heaven and earth, so it is eaten from winter to the sun." In fact, "wonton" and "chaos" are homophonic, so people extend eating wonton to break the chaos and create the world. Later generations no longer explain its original meaning, but spread the proverb "Wonton from winter to the sun, and from summer to the sun", treating it simply as a seasonal diet. On the solstice of winter, people have the custom of pasting "99 cold current map". The map of dispelling cold records that the weather turned cloudy and sunny after entering September. In the coming year, we will become rich and poor. There are many forms of cooling diagram. Generally, nine columns are drawn on paper, each column is drawn as nine coppers, each copper represents a day, and the date is marked next to it, which is exactly 998 1 day (for example, from the previous year1February 22nd to the next year12nd). Brush it every day according to the principle of "painting cloudy days on the top, sunny days on the bottom, rain and snow on the left". Some literati paint nine plum blossoms, each with nine flowers, each representing a day, which is called "elegant painting". Just like the previous method, the rain and snow turn cloudy and clear, and a flower is dyed every day. "The petals are exhausted, and the spring is deep!" Therefore, a couplet is marked in the painting, saying, "Try to see the plum in the painting; The grass outside the natural gate is green. " Some pictures are labeled "Jiujiu Song". If it is bought from the market, the picture is from the southern province, and the book says: "September 19 to 29, I can't call them; On March 27th, reed blew on the fence head (cold wind blew on the fence head to blow reed, a bamboo wind instrument); 4936, sleeping at night is like sleeping outside; In 5945, every family piled salt tigers; 6954, warm in the mouth; 7963, pedestrian clothes list; In 8972, cats and dogs sought shade; 998 1 year, the poor suffered; You have to stretch your feet to sleep, mosquitoes and fleas are coming out. Well, some pictures are homemade, and then the book says, "1929 don't shoot;" Walking on the ice in 3949; 5969, Yangpo looked slippery; Seven or nine rivers open, and eight or nine geese come; 99 years without thinking; 99 plus 19, plowing cattle everywhere. "In addition, there are nine words written by the double hook method, nine strokes per word, one stroke per day, and after one stroke, spring comes. Although the form is elegant, it can't express the ups and downs. After entering the ninth year, some literati engaged in so-called activities to reduce the cold, and chose a ninth day, where nine people drank (the homonym of "wine" and "nine"), and nine dishes and bowls were served on the table. Those who finished the table used "nine flowers" to sit on the table, in order to get the meaning of reducing the cold in the ninth year. (spring for ordinary people)
