彼岸花的微笑为人知晓
[bĭ àn huā de wēi xiào wéi rén zhī xiăo]
Based on Chinese legend about the Red Spider Lily, blooming on the route to afterlife, smiling flowers suggest positive emotion hidden behind a story of parting; indicating rare joy or understanding of one's otherwise unknown loneliness, struggle, or bittersweet experience.
