It collects the detailed thoughts behind all the stories written in the pen that cannot be included in the text.
It contains the origin of the creation at the beginning of writing, the closing remarks at the end of the song, miscellaneous notes on literary and historical research, idle thoughts while sitting at the desk, and essays on the mood of the four seasons related to the plot.
In the world of immortals, all kinds of separations, joys and sorrows are spread out on the long scroll, leaving only a clear word to record the author's obsession, regret and the tenderness and joy in his heart hidden in the pen and ink.
Intention: to record the creative thoughts, retain the words and emotions behind the story, send the wind and moon with essays, and keep the pure original intention of writing.
