If you are sitting on a seat on a subway and see an old woman faltering getting on the train, what would you do? Will you get up from the seat and give your seat to that old woman, or just ignore her? In China, most of the people do the first one, becauce you will feel so embarrassed if you don't give your seat to that old woman. In Korea, it is totally different. There is special seats in each section of the train for the elders and weak people, so they don't need to give their seat out!
