"Rain Alley" by Dai Wangshu, the "Rain Alley Poet" in Hangzhou: Holding an oil-paper umbrella, wandering alone in the long, long/and lonely rain alley/I hope to meet/like a lilac/with sorrow The resentful girl... The poet created a lilac-like girl with a resentment in "Rain Alley", which gave people a hazy and deep sense of beauty. From then on, the oil-paper umbrella represented resentment, hesitation and sadness. . Since then, oil-paper umbrellas have become synonymous with Hangzhou’s hazy, classical and melancholy beauty. That kind of deep love that comes leisurely from ancient times, that softness, that softness, that tenderness that makes people melt.
