When I went abroad, I understood what cultural diversity means. The poster refers to the diversity of cultures represented by various butterflies, because flocks of butterflies remind me of various cultural groups existing next to each other, living sometimes in a hurry but respecting each other. Next, the butterflies' colourfulness symbolizes the diversity of languages, ideas, arts which constitutes the fundamentals of cultures. Butterflies fly from human hands as culture is the creation of a human being and by humans it is cultivated and protected. Finally, the overall shape of the group of butterflies suggests a shape of Earth.
