Teacher's day in Korea

During the may have many special day for example children's day, parent's day, teacher's day and Buddha's birthday. 
Today is teacher's day in Korea. Usually, in this day, we give some present or flower but nowadays we cant't give to them because, some rich children's parents are giving high quality gifts witch will be bribe. So nowadays just we pay together and we buy one present for teacher. 
Nowadays teachers has many problem about students because, teachers can't control at students. I think more grow up about education system in Korea.


Thank you for teach.
