To tell the truth, there are still many differences between the north and the south in winter. For example, the north, especially the northeast, is basically ice and snow. In fact, it is difficult to find ingredients, unless there are some sunny days after snow to find game food, such as rabbits, and some squirrel holes, where some pears and hazelnuts may be stored for these small animals to eat in winter. There may be some mushrooms that resemble fungi, but I'm not sure if they are easy to find. After all, it's too cold outside. Winter in the south is richer than that in the north, because the temperature is not lower than zero, so many wild fruits and vegetables can still be seen, and there are too many ingredients for small animals in the south. The key is to see what kind of field you are in. Some wild areas are still inhabited. You can go to places where people live to see people and change some ingredients. It will be much better to go back. The key is to look at everyone's ability, which may not be comprehensive in general.
