2. Whether boys send chocolates or girls send chocolates, they can generally be divided into two types: reasonable chocolates and love chocolates. Chocolate given by friends and relatives is called sensible chocolate. For example, elders give it to younger generations on Christmas Day, or younger brothers and sisters give it to older brothers and sisters, or good friends give it to each other (including friends of the opposite sex). In addition, the chocolate given between lovers is called love chocolate, which represents the sweetness and intensity of love. Valentine's Day is a custom from somewhere in England. There will be a big party on Valentine's Day! Men and women who love each other will express their love on this day, and boys will send roses to girls to express their love! A girl who symbolizes pure love will send chocolate to express it! Express sweet love! March 14 is white day. White day is popular in Japan, South Korea, Taiwan Province and other regions. It is a continuation of the Western Valentine's Day as we know it, and it is also different in terms of gifts: specifically, on February 14, women send men chocolate, and on March 14, men will send back a gift. Actually, White Day, or White Day, originated from Japanese folklore: February 14 Valentine's Day was originally a day when girls appealed to boys for affection, and girls gave boys Valentine's Day chocolates. In Japan, which is still a world of male chauvinism, most girls give gifts to show their love to their sweethearts on February 14. If the man is interested, he will return the gift on March 14 to show that the two sides are soul mates. But in Hong Kong, Taiwan and other places, the distinction between men and women is not so obvious. On March 14, a lover's gift was sent back to the other party, which means that we have mutual affinity.
