     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 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 profession 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 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), join the army and (in Britain) drink

alcohol or buy a house. In many English-speaking countries, a twenty-first birthday cake often has a key on

top, or the cake itself is sometimes in the shape of a key. The key mean8 that the young person is now old

enough to leave and enter the family home at any time they want to!
