Most people have had campus experiences, and each era represents a slightly different campus culture. As an experienced person, the author will show the culture of the campus where he lives from his own perspective. I hope all readers can find their lost youth here. The article is a bit one-sided, and I hope readers will understand. If there are more people reading it, I will publish it and correct the shortcomings; if it goes nowhere, I hope all readers will not complain.
Intention: There is nothing that can't be overcome, it's just that you can never go back.
