Chinese cabbage has been introduced into China for nearly a hundred years. Although it has not been transplanted to China for a long time, it has been widely planted in the north and south of China and inside and outside the Great Wall, and has become one of the favorite vegetable varieties because of its strong adaptability, long supply period, high yield, storage resistance and convenient transportation. After years of planting, there are many varieties of cabbage. Such as common Chinese cabbage, Brussels sprouts, kale and broccoli.
