This novel contains the author's story. In fact, not everyone's youth is vigorous. There is no good or bad evaluation of youth. Whether it is enthusiastic or dull, it is a part of you. You will remember and express it many years later. As a post-90s generation who has late marriage and late childbearing, the author's youth may have been dull like most people's. However, occasionally there are still some different notes in life that will jump out. Record your youth and see if there is any shadow of you. . .
