Which is better to keep pork fresh in winter, outdoor storage or freezer freezing?

The freezer has two floors, one for safety and the other for freezing. The freezing effect of freezing layer is good, and the preservation effect of fresh-keeping layer is good, but the preservation effect of freezing layer is not as good as that of fresh-keeping layer.

Outdoor storage in winter is about equal to fresh-keeping, but the temperature of fresh-keeping is constant, outdoor storage is not constant, and there are more bacteria in the outdoor air, which are easier to attach to meat, and the fresh-keeping effect is greatly reduced.
