What to eat in Suzhou from winter solstice, and the solar altitude angle in Suzhou from winter solstice.
Winter solstice is a traditional solar term in China, but it is unique in Suzhou and Wudi, and people pay special attention to it. This is the legacy of Suzhou's ancient pursuit of the Zhou Dynasty calendar. So there is a saying in Suzhou that the solstice in winter is as big as a year. Suzhou formed the custom of celebrating winter solstice day and night in Song Dynasty. At that time, every family had to worship their ancestors, and the younger generation had to wear new clothes to pay New Year greetings to their elders.
In the traditional folk custom of Suzhou, the daughter-in-law must go back to her husband's house for a winter solstice meal, and each family hangs a portrait of their ancestors as a memorial. The younger generation also went to their elders' homes to pay New Year greetings, saying that they would celebrate the holidays and worship the winter, and all the etiquette was the same as that of the New Year. In the night from winter to Sunday, Suzhou people are also very particular about their staple food, and there is a saying that "wonton is from winter to Sunday and noodles are from summer to Sunday". The ancients said that the sky is round and the earth is round. The square wonton skin represents the earth, and the stuffing in the tundish is the sky, which is an inseparable and seamless "chaotic world". People eat "wonton" on the winter solstice, which means eating the "chaotic world" and making it a clear world.
