What year was "What a Hibiscus" written?

This article was written in May, 1982. At that time, the author's younger brother was terminally ill, and the author was very sad (the younger brother died in June, 1982). He walked in the courtyard and saw a blooming wisteria flower, which made him feel relieved. He realized the beauty of life and the eternity of life, so he wrote this article.
