Why do you eat rice cakes on the solstice in winter?

It is said that in the winter of solstice, there was a man who had a lot of grain in his house. Then he made bricks out of these grains and built the walls of his house. Later, in the famine year, the people tore down the wall of his house and took out all these bricks to eat. This is the rice cake, which has been handed down to this day.

The solstice in winter has two meanings: nature and humanity. It is not only an important solar term among the 24 solar terms, but also a traditional folk ancestor worship festival in China. The solstice in winter is one of the eight festivals in four seasons, and it is considered as a big holiday in winter. In ancient times, there was a saying that the winter solstice was as big as a year. The custom of winter solstice varies in content or details due to different regions. In southern China, there are customs of offering sacrifices to ancestors and enjoying the winter solstice. In northern China, it is a custom to eat jiaozi from winter to Sunday every year.
