February has long been a month of romance. With the sweet smell of roses in the air, romantic films hit cinemas and love stories fill newspapers and magazines.

On the 14th day, it is a custom for a boy to take his girlfriend out to dinner, buy her flowers and chocolates, write poems, sing to her or even spell out her name with rose petals(花瓣)! This is the scene that greets you on Valentine's Day, named after Valentine who was a priest (牧师) in third century Rome. When the emperor（皇帝）decided that single men made better soldiers than those with wives, he didn’t allow marriage.But Valentine continued to perform marriage ceremonies for young lovers in secret. When his actions were discovered, the emperor had him put to death. While in prison, it is said that Valentine fell in love with the daughter of his prison guard. Before his death on 14th Feb 270 DC, he wrote her a letter, which he signed ‘From your Valentine’, an expression_r that is still in use today. Valentine died for what he believed in and so was made a Saint(圣徒), as well as becoming one of history's most romantic figures.

Nowadays, Valentine’s Day is also popular among Chinese young people. Some students are planning to make Valentine’s cards for parents, teachers and friends.
