Qiu Xiaomu's experience condenses a society where everyone can find their own shadow. The memories of childhood, childhood and adolescence are reappeared in large pages, depicting the common years that the 80s generation spent together. Nowadays, the post-90s are in power, and the post-80s are gradually fading out of the Huacai historical stage and relegating to the second line. At the age of thirty, maybe they have been refined, or they are still looking for it, or they have become numb. The only thing that is certain is that their youth is no longer flowing. I would like to use this article to mourn and remember with the post-80s.
