I remember that I didn't eat anything but cabbage in winter at home, which was very depressing. Now I'm much better, and there are more greenhouses.
There are many kinds of winter vegetables in Guangdong, but they are also quite expensive, with 2-3 pieces of green vegetables and 3-4 pieces of cucumbers and tomatoes.
Southerners seldom eat cabbage, and it is not Chinese cabbage in the north, but local Chinese cabbage. I guess they dare not eat such a big cabbage in the north.
