A special set of four stamps featuring fruits are released by China Post on July 15, 2014. Priced at 5.4 yuan ($0.87) per set, each stamp contains the scent of the fruit pictured - peach, apple, pomegranate or kumquat - as a result of fruit-scented ink.
The peach (Prunus persica) is a deciduous tree, native to Northwest China, in the region between the Tarim Basin and the north slopes of the Kunlun Shan mountains, where it was first domesticated and cultivated. It bears an edible juicy fruit also called a peach.
Apples have been grown for thousands of years in Asia and Europe, and were brought to North America by European colonists. About 69 million tons of apples were grown worldwide in 2010, and China produced almost half of this total.
Introduced to China during the Tang Dynasty , the pomegranate in olden times was considered an emblem of fertility and numerous progeny. Pictures of the ripe fruit with the seeds bursting forth were often hung in homes to bestow fertility and bless the dwelling with numerous offspring, an important facet of traditional Chinese culture.
China is one of the world's leading producers of kumquats. Indeed the earliest historical reference to kumquats appears in Chinese literature in the 12th century, and the plant was native to China before it was spread to Japan, Taiwan and South America.
