Guangdong is located in a city in the south of China, where the temperature is very suitable in winter. However, most southern cities eat glutinous rice balls on the winter solstice, and a bowl of warm glutinous rice balls is enough to make the slightly cold winter feel warm.
In northern cities, jiaozi is often eaten during the winter solstice.
No matter what kind of food you eat, it is a feeling of joy for the festival and gratitude for a better life.
