?For someone from China's Hong Kong SAR, giving two of something, or a pair, carries better luck than a single item. ?Among Latin Americans, the gift of a knife or knives suggests the “cutting" of a relationship; yet this notion can be blunted by including a coin with the knives. ?In the Middle East, a handkerchief suggests tears or parting, and therefore is inappropriate as a gift. ?Flowers carry all kinds of symbolism: purple flowers are the flowers of death in Mexico and Brazil; the same with white flowers in Japan; and white chrysanthemums are the flower of death in many European countries. Also, it is considered bad luck in many European countries to present an even number of flowers. Therefore, always present an odd number (except for 13, of course). ?When you present flowers to a person from Germany, always unwrap the bouquet first.
