Different countries have different customs in giving presents.
In China you must never give a clock to a Chinese person, because the sound of the word"clock" is similar to the sound of"death". Also, don't wrap(包,裹)a present in white, black or blue paper, because they are the colours for funerals(葬礼). Don't give a knife, because something sharp can cut a friendship.
In Russia if you give flowers as presents, you have to give an odd number(奇数) of them(one, three, five, etc.) because even numbers(偶数) of flowers are for funerals.
In Germany if you are invited to dinner, a bunch of flowers is a good present to take to your dinner hostess (女主人), but don't take her red roses because it means you are in love with her. Don't take thirteen of anything because it's an unlucky number. Don't take an even number of anything, either. Don't wrap your presents in white, brown or black paper.
