    Do you still remember the debate(讨论) between sweet and salty zongzi during Dragon Boat Festival? It seems that the differences between northerners and southerners have always been a popular topic among Chinese. Now another difference has drawn wide attention: The way northerners and southerners shop for food at markets.

People from southern China might say they prefer to buy what they need for just one or two meals. It is normal for them to buy just half 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, reported China Daily.

Also, when you go to the market in the south, you can buy a small amount of fruit, such as an apple or pear. Shop owners even help you peel and cut them. But hardly do shop owners in the north offer such service.

The difference could be because of the different weather.

Food can be kept for a long time in the north, as it is usually cold and dry there. Many northerners have the habit of stocking up（储存）on food.

But because of the hot and wet weather in the south, southern Chinese prefer to buy just enough food for one meal or one day. Otherwise, the food may go bad.

Maybe these debates about differences help us Chinese know more about each other.
