In many parts of northern China, it is a custom to eat jiaozi every winter solstice. According to legend, Zhang Zhongjing, a medical sage, saw a frozen person when he retired in his later years, so he wrapped mutton, some cold-dispelling herbs and dough into the shape of ears, made a medicine called "Quhan Jiaoer Decoction" and gave it to the people. Later, on the solstice of winter, people imitated eating and formed a custom. ?

The solstice in winter is a good time for health preservation, mainly because "Qi starts from the solstice in winter". Because from beginning of winter, life activities began to turn from decline to prosperity, from static rotation. At this time, scientific health preservation helps to ensure vigorous energy and prevent premature aging, thus achieving the purpose of prolonging life. During the winter solstice, the diet should be diversified, grains, fruits, meat and vegetables should be reasonably matched, and foods with high calcium should be selected appropriately.

In winter solstice, different places have different customs, and most places in northern China have the custom of eating jiaozi in winter solstice. After thousands of years of development, a unique seasonal diet culture has been formed from winter solstice to Sunday. Eating jiaozi has become the winter solstice custom of most northerners in China. Of course, there are exceptions, such as the custom of drinking mutton soup from winter solstice in Tengzhou City, Shandong Province, which means driving away the cold.
