I have a couple of questions on the changing of the guard cermeony at Gyeongbokgung. 1.) Could you explain the significance of the various banners used in the changing of the guard ceremony? 2.) Does this ceremony as currently performed date to the 15th century (early Joseon)? 3.) To when do the clothes date? 4.) What meaning do the colors of the various clothes have? 5.) Is the language being spoken by the captain/sargeant an older form of Korean? 6.) To what century do the instruments date? 7.) How old is the music that they are playing? 8.) Of what were the guard's clothing made during early Joseon? Silk and ramie? something else? Thank you! :-)
