This is Zheng Yanhe's story, and it is also the story of you and me; it is her city, and it is also your and my city. They are all small people, and they are our youth.
I have watched too many youth-themed movies, novels, and TV series, and listened to too many people's stories late at night. I was afraid that they would forget their beautiful youth, so I wrote down Zheng Yanhe's story.
For those who are willing to stay with me late at night. I hope they and they will stay young forever.
