Explanation:

Coming-of-age day is a special day that marks the moment when individuals stop being children and become adults. This day is held through a ceremony where everyone wears traditional Korean clothes and bow towards their country in thanks for their care in childhood. Parents, in turn, bow towards their children, showing respect for the adult life they will have. Although this ceremony is losing its popularity it is still possible to see it being performed, including the participation of foreigners who can attend and participate in the activities.

It is a tradition that on that day young people get flowers and perfume, but nowadays they are allowed to choose their gifts.
