China covers large areas and has a large population. Different living habits have always been interesting topics in the country. Recently, another difference between southern and northern Chinese has become a hot one: the way people shop at markets.
People from southern China say that they always buy what they need for just one or two meals. It is normal for them to buy half of a Chinese cabbage, two potatoes and 0.25 kilograms of beef at a time.
However, one may be laughed at if he does this in the north. Instead, buying vegetables and meat enough for a week is usual. Also, you can buy a small amount of fruit, such as a single apple or pear, each time in the south. Shop owners even help you peel and cut them. But shop owners in the north hardly offer such service. And many fruits are sold in baskets and boxes.
The difference could be due to the different weather. Food can be kept for a long time in the north, as it is usually cold and dry there. Many northern Chinese have the habit of storing food, especially for the long winter. But the hot and wet weather in the south makes southern Chinese buy just enough food for one meal or one day, or the food may go bad.
