The first difference: the difference in diet and geographical environment between the north and the south has created the difference in diet culture between the north and the south. As we all know, the main food for hunger in the north is pasta, while the main food in the south is rice. When a southerner who is used to eating rice comes to the north to eat noodles and steamed bread, it is easy to form a gap. Although most schools have rice in the canteen window, the price of rice is slightly more expensive than steamed bread, and most southerners still choose steamed bread with reasonable price.
The second difference: the difference in climate has led to the formation of a huge food culture in the north and south because of the different climate. The north has a temperate climate, while the south has a tropical climate. This caused me to feel cold and unable to get warm after I came to the north to study in college. What's more, the winter in the north will reach MINUS ten degrees, which makes it even more unbearable for southerners to bear the cold weather.
The third difference: northerners and southerners have different personalities. Before I came to the north to study in university, there were always southerners around me. They spoke very quietly and said they were gentle. Since I came to the north to study in university, my friends around me are generous and stubborn. Because I spend too much time with my northern friends, I have the same personality characteristics as southerners and northerners. In short, if you want to try a different life, you can choose to go to college in the north.
