Rain Lane is a famous work by Dai Wangshu. By describing the narrow and gloomy rain lane, the lonely traveler wandering in the rain lane and the girl as sad as lilac, the author implicitly implies that the author is confused and sad, giving people a hazy and profound aesthetic feeling.
Some people interpret these images as a microcosm of the dark society at that time, or as people who failed in the revolution and hazy and intermittent hopes.
