This article is based on the true story of Bai Qi in Nankang. Please forgive me if there is any offense. It is recommended that you read "Six Chapters of a Floating Life" and "I Wait for You Until You Are Thirty-five" by Brother Nankang before reading this article. This article is mainly adapted from the two essays mentioned above and the diary of Brother Nankang. There are many quotes from the original text, so please don't be surprised. It's not well written, so I'm sorry to everyone.
