Xiangyun are traditional Chinese stylized clouds decorative patterns. They are also known as yunwen, auspicious clouds or lucky clouds. Xiangyun was also introduced in Japan, where it became known as zuiun. In Chinese culture, clouds (especially the five-colored clouds) are perceived as an auspicious sign (e.g. an omen of peace), a symbol of Heaven, and the expression of the Will of Heaven. They also symbolize happiness and good luck. In Chinese mythologies, mythological creatures and deities use clouds as their mount. Clouds were also closely associated with the Chinese immortals (called xian) and their residence on Mount Penglai. Xiangyun were also symbolic motifs which implied immortality - Wikipedia.
