What are some things you didn't know until you went to Beijing?

I am a college student who arrived in Beijing from a southern city to go to school. I went to Beijing for the first time and lived there, and I learned a lot of things that I didn't know before. For example, what floats in the sky in spring is not dandelions but willow flakes; and the chips that you can't finish on the first day can be eaten on the second day, and so on.

The first spring in Beijing, I saw the white flakes flying all over the sky. The fluff? , I was so happy to think there were so many dandelions in the north. It was a scene I had never seen before in my home in the south, and I found it very novel and fun, and went out to shoot a couple of outtakes. It wasn't until one time when I was in gym class on the playground that I said to my class: ? Why are there so many dandelions here? I've been watching dandelions float in the sky for days. My words drew laughter from everyone around me. After their explanation, I realized that the dandelions in Beijing's winter sky are not dandelions as I thought, but willow flakes. I suffered so many days of willow flakes that my respiratory problems were so bad that I had to wear a mask when I went out.

Because I've always lived in a cold, damp southern city, I've gotten used to the idea that chips I can't finish on the first day can't be eaten on the second day because they're all soggy. When I first arrived in Beijing, I didn't realize that opened potato chips could be kept overnight. Once I was eating potato chips in the dormitory, and I couldn't finish a big bag, so I asked my other roommates to work it out. You guys finish them quickly today or you won't be able to eat them tomorrow and waste them.? They asked me? Why can't you eat them? Because it's damp. They also told me that north so dry is not damp, so the chips can continue to eat even if you put them tomorrow.

Because of the social environment of different regions and cultural differences, the first time the southern girls living in Beijing for a long time, know a lot of things that were not known before.
