[0002] Generally, the vegetable planting and production areas are not in the same location as the vegetable processing and consumption areas, that is, vegetables need to be transported. During the transportation of vegetables, especially during long-distance transportation, in order to reduce problems such as vegetable spoilage, the prior art often uses a fresh-keeping box to protect vegetables at a low temperature.
