Why isn't frozen vegetables more popular?

In the past two months of fighting the epidemic at home, I have profoundly felt the difficulty of buying vegetables, the difficulty of buying fresh vegetables, and the preservation of fresh vegetables. Moreover, many fresh vegetables donated to Hubei after watching the news also deteriorated and spoiled. Some of the fresh vegetables even broke during transportation, and the vegetables shipped to Wuhan required a large number of people to sort, wash, and store them. It also consumes a lot of manpower, material and financial resources.

At this time, it is possible to show how important it is to store vegetables in good quality and fresh. These frozen vegetables are processed after picking and then quickly frozen for frozen storage. After buying, they only need to be stored in the refrigerator to freeze and then thawed when cooking. .
There are many such frozen vegetables sold abroad, and they are still very good. Why is it not popularized in China?
Frozen vegetables have been stored in the refrigerator from time to time, such as broccoli, okra, corn, green beans, etc., thawed and cooked when needed, it is very convenient and delicious. Frozen vegetables can bring a lot of convenience to life at critical moments.
