We saw the changing of the guard. The changing of the guard happens once an hour. The guardmen had to stand for an hour and they were not allowed to move at all on duty. I wondered what they would do if they suddenly got a stomachache. Do they have an SOS signal? And we were surprised that there were some security staff who were policing the guardmen. They were often adjusting the appearance of the guardmen and fixing crease in their uniforms!!
