Beijing’s food culture is closely related to its geographical environment.

Here are some main connections: 1. Grain structure: Beijing is located in the North China Plain, which is suitable for growing wheat, corn, millet and other crops. Therefore, pasta, cereals, polenta and other foods are more common in Beijing’s diet.

2. Vegetables and fruits: Beijing is located in a temperate continental climate zone, which is suitable for growing various vegetables and fruits, such as cabbage, radishes, cucumbers, tomatoes, spinach, leeks, etc. These ingredients often appear in Beijing’s diet.

3. Meat and aquatic products: Beijing is close to the Grand Canal and the ocean, so aquatic products and animal husbandry are relatively developed, such as pork, beef and mutton, fish, shrimp, etc., which also play an important role in Beijing's diet.

4. Food taste: Beijing is located in the north, and the taste is heavy, especially the amount of salt and oil used. This may be related to the cold climate to increase the heat in the body.

In short, Beijing’s food culture is inseparable from its geographical environment, and this connection determines the characteristics and flavor of Beijing cuisine to a large extent.
