花开花落彼岸花
[huā kāi huā luò bĭ àn huā]
'Hua Kai Hua Luo Bi An Hua' means 'the flower blooming and falling: Fleeceflower,' with 'Fleeceflower' (a metaphor) standing for a flower believed to bloom once every three years, whose leaves and blossoms never coexist at the same time. It conveys ideas like transience and unreachable aspirations or people.
