February 14 is a day for people who have fallen in love. On this day, these men and women give gifts (presents)and cards to each other for Valentine's Day(情人节).This day has been popular with people in love  for a long time. At first，this holiday was called Lupercalia. Then the name of the day was changed to Saint Valentine's Day. The man named Saint Valentine was killed on February 14，270 AD, because he was a Christian (基督教徒).

    Before Saint Valentine was killed，February 14 was the old Roman holiday，Lupercalia. The church wanted people to think of a Christian holiday on this day，so the church changed the name of the holiday.

    This change did not stop people in love from giving gifts to each other. People usually gave gloves, handkerchiefs, or even underwear was gifts. Sometimes people also put hearts and flowers on the presents before giving it to the other persons.

    Valentine cards did not become popular until the 1750s. The first Valentine cards were made by hand. People wrote their own words on the cards. These words were usually funny.

    Now, every year around February 14，cards and chocolates fill shops for people in love.
