The day is observed with exchanges of love notes and cards, and other tokens(标志) of affection(感情), called valentines. The symbols of the heart and Cupid(丘比特) are common in cards, decorations of store windows,candies and other paraphernalia(随身物品). Traditional valentines were frilly(装饰的) sweet, and tender(温情的) affairs made of red and white paper and lace(花边) with cutouts(剪下的图样) and cupids.

Doll's Day 女儿节(初)
The third of March is an exciting day for little Japanese girls. They know it as Doll's Day. On that day, any household which has a daughter aged between three and seven decorates the house with traditional dolls. They represent the royal family and members of the court. They are extremely delicate and finely dressed. The dolls may have been in the family for several generations, or they may have been newly presented to the daughter of the house, usually by the grandparents. The little girls do not merely look at the dolls displayed in the house. They themselves are dressed in elaborate kimonos, again of traditional design. Then their parents accompany them to the sacred shrines. After they come back home, special rice cakes are eaten. Doll's Day in Japan is for the girls, but the boys have their own turn later. Their festival occurs on May 5th, and this time the house are decorated with armour, emphasizing a traditional male role
April Fool's Day 愚人节 (初)
April Fool's Day is the first day of April. The sport of the holiday is to play silly but harmless jokes on family members, co-workers, and friends. A victim of one of these pranks is called an April fool. If one succeeds in tricking someone, one laughs and says, `April Fool`, and then the person who has been tricked usually laughs, too. This holiday originated in France. When the French first adopted the Gregorian calendar in 1564, some people continued to use the old calendar to celebrate New Year's Day on April 1.These people were called April Fools. The custom of playing tricks on this day became popular in France and then spread to many other countries. April Fool's jokes are as ingenious, humorous, or cruel as the people who perform them. Here are some typical pranks: __Telling somebody to call the zoo and ask to speak to Mr Fox. __Putting salt in the sugar bowl. __Setting the clock back an hour. __Saying to friends, 'Oh my! You have four holes in your coat-buttonholes! __Trying a string to a wallet and leaving the wallet in the middle of the sidewalk. When someone stops to pick it up, the pranker yanks it out of reach. In the United States today, April Fool's jokes are mostly played by children, who enjoy the holiday immensely.
