"The weather and personnel are urging each other day by day, and the winter solstice brings sunshine and spring again." (Du Fu's Minor Solstice) The winter solstice is the fourth solar term in winter. It falls between December 21-23 of the Gregorian calendar. On this day, the sun directly hit the Tropic of Cancer. The day is the shortest and the night is the longest in the northern hemisphere of the earth. After that, the position of the sun's direct rays gradually moved northward, and the days in the northern hemisphere gradually became longer. It is the so-called "the sun rises at the winter solstice, and a needle grows every day". The ancients understood the seasonal changes with the movement of yin and yang, and thought that "the summer ends at the autumnal equinox, and the spring begins at the winter solstice". There is a folk saying that "one yang is born on the winter solstice". Since then, the two qi of yin and yang have been reversed, and life activities will become more active. The Winter Solstice is not only a solar term but also a festival. It is also called "Winter Solstice Festival", "Asian Year" and "Winter Festival". In ancient times, it was a very grand festival, the so-called "Winter Solstice is as big as the year". Tian Rucheng of the Ming Dynasty recorded in his "History of the West Lake Tour" that "the official and private parties celebrate as if it were the first day of the lunar calendar. Wuzhong is the most prosperous, so there is a theory of" fat winter and lean year " "Fat Winter and Lean Year" means that the local people regard the winter solstice as more important than the New Year, "such as giving gifts to festival ceremonies, and toasting to celebrate the festival", which is very lively. According to the Qingjia Record, around the winter solstice in the Qing Dynasty, there were many friendly visits and gifts between relatives and friends, commonly known as "Winter Worship". The gift box filled with all kinds of festival gifts is called "Winter Solstice Plate". Most of the boxes are food cakes, osmanthus winter wine, dumplings, pickles, etc. The night before the winter solstice is the "winter solstice night". On this night, the family reunited and had a "Winter Solstice Feast" with USUNHOME. In the villages around Taizhou, Zhejiang Province, where people gather together to worship ancestors and have dinner together on the winter solstice, it is called "sacrificing winter". After dinner, the clansmen will offer pork to the elderly over 60 years old, which is called "elderly meat". At the age of 60, they will get a pound of meat. When they grow one year old, they will add an extra pound of meat to show respect for the elderly. There is a custom of eating dumplings on the winter solstice in northern China. It is said that Zhang Zhongjing, a famous doctor, created the "Cold dispelling Jiao'er soup" to cure people's frostbite. Later, people learned to wrap food like "Jiao'er". Over time, the famous "dumpling" was passed down. In the south, there is the custom of "winter solstice dumpling cake". In the old days, the family used flour to make dumplings, and meat, vegetables, cowpea paste, shredded radish, sugar, etc. were used as fillings. After steaming, they offered sacrifices to ancestors and gave gifts to relatives and friends. They were called "Winter Solstice Tuan". In Shaoxing and Jiaxing, Zhejiang Province, people often eat wonton. As the saying goes, "wonton on the winter solstice and noodles on the summer solstice". The winter solstice is also a nourishing season. As the folk saying goes, "Make up for one winter in three to nine, and there will be no sickness in the coming year." "Make up for it in winter, and fight tigers in spring.". In winter, it is better to use ointment. A pair of ointment often contains more than 20 traditional Chinese medicines. It is made by adding water to decoct the medicine, removing the dregs and concentrating, and then adding auxiliary materials to collect the ointment. The cream is as smooth as a cream and as smooth as a paint, with excellent nourishing effect. Since the winter solstice, it has been the coldest day in all parts of the country, which is often called "entering the ninth lunar month". From then on, every nine days counts as a "nine", and so on. By the end of the ninety-nine eighty-one cold days, spring has come, which is commonly known as "nine consecutive winters". In the long and bitter winter, there is a very interesting game - fill in the "Jiujiu Cold Relief Map". The common cold dispelling picture is a double hook red calligraphy, with nine characters of "weeping willows in front of the pavilion cherish the spring breeze", all in traditional style. There are nine strokes for each character, 81 strokes in total. From the winter solstice, one stroke is drawn every day according to the stroke order, and every "19" is finished
