March 14 is white day, which is generally considered as a continuation of Western Valentine's Day and originated in Rome in the third century. Legend has it that the Roman emperor set up Valentine's Day to commemorate that he saved a pair of lovers who were about to be executed for violating the prohibition of love and marriage in February 14. A month later, in March of 14, the couple vowed to die till death do us part, and this day became white day today.

"white day" originated in European countries, and was accepted and widely spread by the Japanese in 1970s. Gradually, "white day" became popular in Japanese, Korean, Taiwan Province and other regions, which is a continuation of the Western Valentine's Day as we know it.

Europeans have a certain history of "White Day" and have formed an appropriate and mature custom. According to legend, in February of 14, boys gave girls gifts (usually roses and chocolates). After a month's consideration and investigation, on March 14, if a girl gives a boy a gift (usually handmade cookies), it means that a girl recognizes a boy and can fall in love.
