It is a story that the author likes very much. Although it is full of pessimistic, negative, and world-weary emotions, it does indeed reflect the spiritual emptiness of modern people. The life of modern people, on the surface, seems to be colorful and varied, but in fact, it is poor and boring, and the same.This kind of life has formed an extreme spiritual dissatisfaction, and the life of humans and insects can be equated, so the tragedy becomes superficial. The idea in the story is the author's point of view before he has a further view on life, which has been maintained for many years.
