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.
It was just by a chance that I got to know there are peacocks in a nearby shrine. Then, I searched for a haiku and a poem from ancient China with a “peacock” motif. I soon found both but they both are poems on spring season, which means I was a little late to do this.
