Legend has it that the blooming of platycodon flowers represents the return of happiness, but some people can catch happiness, but some people are destined to miss it, unable to catch it and unable to keep the flowers. Therefore, Platycodon has a double meaning - eternal love and hopeless love. When the platycodon flowers bloom, they represent a state of mind looking back at everything on the road to youth, called no regrets. What I once thought was hopeless, under the pull of fate and the persistent pursuit like a thorn bird, finally became eternity.
