[April, 2011] This photo was taken in front of a palace in Seoul.
It was a ceremony like change of the guards.
I am not sure it was something they has been doing for ages historically, or they have started recently mainly for tourists.
In fact, we saw a similar event at another palace and also at the airport, people dressed up as some royal family and marched around.
To be honest, I do not anything about Korean history, and I wonder because it is not well-known, they are trying to show it so hard.
