南方人买菜买一顿，北方人买菜买一吨！
Thanks to the large territory(领土) and huge population of China, differences of living habits and geographical features have been an ever-lasting topic among Chinese. Unsurprisingly, netizens went wild again as they recently discovered another striking difference between the country’s northerners and southerners: the way they shop for food.
According to netizens from southern China, they usually buy what they need for just one or two meals. “It is quite normal for us to buy one or half of a Chinese cabbage at a time,” said a netizen. However, one is very likely to be laughed at if he does this in the north. “We love to stock up(大量储备) on groceries. Buying 25 kilograms of Chinese cabbage is quite usual,” said a netizen from the north.
Moreover, in the south, it is said that winter melon is always sold in chunks. “One chunk is enough for two meals!” one said. While in the north, it is simply not possible. “Of course we buy a whole one, or nobody is willing to buy the other half,” said a northern Chinese.
Because of this, cultural shocks certainly cannot be avoided. Experts say that the difference is due to the different climate. Groceries can be stored for a relatively long time in the north as it is usually cold and dry there. However, the hot and wet weather in the south makes southern Chinese to buy just enough for one meal or one day, or it might go bad.
