Chinese cabbage is a kind of road vegetable, which has a wide range of eating habits in southern China. In the north of China, the production area is very small, and the consumption is also very small, which belongs to the ranks of rare special vegetables. Chinese flowering cabbage cannot be developed in the north for the following reasons: Spring and summer are suitable for Chinese flowering cabbage planting, but northerners like to eat fruits and vegetables. At this time, fruits and vegetables are on the market, and vegetables such as cucumber, tomato and eggplant squeeze cabbage out of the market; In autumn, Chinese cabbage has a high yield, is easy to cultivate, and people like to eat it, which is incomparable to Chinese cabbage. Chinese cabbage can't be planted in large quantities instead of Chinese cabbage. Chinese flowering cabbage has the advantages of continuous growth in winter and continuous harvest and supply in the south of the Yangtze River, but the cold in the north makes this advantage impossible to play.

With the rapid development of social economy and frequent personnel exchanges, especially the rapid development of Guangdong economy, Guangdong personnel are spread all over the country. As a result, Guangdong people's living habits and food requirements have gradually spread to all parts of China. Their favorite dishes, starting from hotels and restaurants, have gradually expanded to the market, and the demand is increasing. This social demand naturally stimulated the development of production.
