The winter in Northeast China is cold, with heavy snowfall. Goose is a kind of poultry adapted to the cold climate. Goose is delicious, fat but not greasy, and is regarded as delicious in winter by local people.
In addition, the farming culture in Northeast China also influenced this custom. There is a saying in farming culture that "jiaozi is eaten in winter and Laba porridge is eaten in Laba", which means that people need food to increase energy and keep warm in cold winter. Goose, as a high-protein and high-fat food, can provide rich nutrition and calories to meet people's needs.
Therefore, eating geese when it snows in the northeast has become a traditional custom of local people, and it is also a way for people to enjoy food in the cold winter.
