During the weekend, I’ve seen many small shops and stores selling flowers, especially carnations, even on holidays. I have been wondering for several days and now got the answers from some friends:
Today, May 8th is “Parents’ day” – “어버이날” – in Korea. All children will show their parents love, respect, gratefulness, and also their promise to protect them, like the parents always do for their children. The traditional presents to give are red carnations.
