The tradition of birthday parties started a long time ago. There are some traditions that you can find almost anywhere, anytime, such as sending birthday cards, blowing out the candles(吹熄蜡烛) on a birthday cake and singing the ‘Happy Birthday’ song. Others are only found for certain ages and in certain countries.

In China, on a child’s second birthday, family members put many things on the floor around the child. According to Chinese tradition, the first thing that the child picks up tells you what job the child will choose later in life.

For Japanese children, the third, fifth and seventh birthdays are especially important. At this age, there is a special celebration(庆祝) Shichi-Go-San (seven, five, three in Japanese) when children go to the temple wearing a new kimono (和服). The priest (僧侣) gives them special sweets, and the parents usually organize a party for their friends in their home.

In Argentina, Mexico and several other Latin American countries, girls have a special birthday celebration when they reach the age of fifteen. After a special ceremony (仪式), the girls dance a waltz with their father and other boys.

Eighteen is the traditional ‘coming of age’— the age when (in many countries) you have the right to vote (选举权), join the army (参军)and (in Britain) drink alcohol (酒)or buy a house.
