Is there anything you didn’t know until you went to Beijing?

I am a college student who came to Beijing from a southern city to study. It was my first time to go to Beijing and live in Beijing. I learned many things that I didn’t know before. For example, the sky full of spring is not dandelions but catkins; you can continue to eat the potato chips you couldn't finish on the first day on the second day, etc. Catkins flying all over the sky in early spring

My first spring in Beijing, I was very happy to see the white fluff flying all over the sky, thinking that there were so many dandelions in the north. This was a scene I had never seen at home in the south. I found it very novel and fun, and even went out to shoot a few outdoor scenes. Until one time when I was taking a physical education class on the playground, I asked my classmates: Why are there so many dandelions here? I have been watching the sky full of dandelions for several days. ?My words made everyone around me burst into laughter. After their explanation, I realized that the things floating all over the Beijing winter sky were not dandelions as I thought, but catkins. I suffered from catkins flying all over the sky for many days in a row, which made my respiratory tract very uncomfortable and I had to wear a mask when I went out. Opened potato chips can be kept overnight

Since I have always lived in a cold and humid southern city, I have become accustomed to eating too many potato chips on the first day and not being able to eat them the next day because they are already wet. When I first arrived in Beijing, I didn’t know that opened potato chips could be left overnight. One time I was eating potato chips in the dormitory. It was a big bag and I couldn't finish it, so I asked my other roommates to help me solve the problem. ?You finish them quickly today, otherwise you won’t be able to eat them tomorrow and it will be a waste. ?They asked me? Why can't I eat it? ?Because it’s damp. ?They also told me that the north is so dry that it won’t get damp, so the potato chips can be eaten even if they are left until tomorrow.

Due to the social environment and cultural differences in different regions, the southern girls who lived in Beijing for a long time for the first time learned many things that they did not know before.
