The Korean See-saw.
I continue to read about Korean etiquette, and it does seem quite worryingly complicated. As I read I wonder if some of this applied in China and how many people I insulted by sitting at the wrong time, eating a certain way, bowing insufficiently (in fact I can't remember bowing very much at all).
The cultureshock book ends with an interesting resumé on Korean games including one called the 'Neolttwigi' or see-saw. I decided to see if there was a demonstration on Youtube and of course there was. It is traditionally a past time of women and a result of their being confined to the family compound: if they bounced high enough they were able to see over the wall.
