In the novel, Sister Lan Fen's death reflects the fragile friendship and kindness in human nature, and also reflects the imperceptible cool thin in daily order. Yin Xueyun's language is light and restrained, and even in the face of such topics as life and death, novelists do not pursue strong colors. In her works, the days are slowly flowing, and the delicate feelings between people are also experiencing scouring and killing. It is this slowness and fragmentation that approaches some truths in real life.

The novel Sister Lanfen begins with a legendary life and death event and gradually involves the secrets of history, emotion and human nature. It was born in a solid and magnolia land, but it rose in the air with an unobtrusive lightness. At the end of the novel, Sister Lanfen hangs from a tree that was honored many years ago. No one knows how she hanged herself, and no one seems to care anymore.
