This is a passage from an old-time Chinese poem about chrysanthemums’ fragrance. Apparently, it expresses moon lit chrysanthemums, insects’ chirping, chrysanthemums’ fragrance, namely, a variety of autumnal beauties competing with one another.
It is a brief extract from a poem by Su Shi in the Northern Song dynasty in ancient China, a major personality and poet. Apparently, it is about a gusty evening shower that comes suddenly and then stops quickly. Now I recall evening showers in summer were just like this when I was growing up. Rains should fall in this manner.
