Flowers, nature's fashion models, became part of China's rich and extensive cultural heritage-- when in the Tang Dynasty flower arranging appeared as an art form. During the Sung Dynasty flower arranging grew in popularity and developed as a formal art. Chinese floral art expresses the Chinese love of nature, complacency, and freedom as well as truth and goodness in beauty.　　To focus on this aspect of traditional Chinese culture, a set of 〝Chinese Flower Arrangement Postage Stamps〞was released.
