What kind of experience is it to live in first-tier cities such as Beishangguang since childhood?

But when I was a child, I ate delicious breakfast, and my friendly and familiar neighbors looked at the busy high-rise buildings built from snacks bit by bit, and felt very happy living in this land. When I grow up, watching people from all over the world pour in, whether it's foreign businessmen from Taiwan Province Province and Zhejiang Province or migrant workers from Henan Province, I know that my kind hometown is no longer mine. I am familiar with the lively, convenient and fast-paced life. When I go to a quiet city or town for my holiday, I will feel temporarily calm and extremely comfortable. However, after living there for too long, I still miss the prosperity of big cities. Sometimes, even watching the traffic and people coming and going at night and the scene of the lights on, I feel extremely cordial and happy. He can't read, he hasn't even been to farmland, but he knows the food and snacks of various countries like the back of his hand. I feel that only the plane that goes directly to my hometown is called a direct flight, and I don't understand the difficult process of taking a train plane and then taking a bus or plane back to China. There are too many people in big cities, ordinary citizens, exquisite petty bourgeoisie and young artists. So I won't write because I just want to write about big cities, not myself.
