I think the custom foods suitable for the heavy snow season are as follows: 1. Mutton: to repel cold and nourish, enhance the ability to withstand the cold, and promote blood circulation.

2. Red sticky porridge: It harmonizes the stomach, nourishes the spleen, and moisturizes the lungs. It is an excellent choice for health preservation.

3. Duitanger: A unique custom food in Wenzhou. Caramel workshops in various places provide the full-page caramel made to small vendors, commonly known as "Tangerke".
