Shot at Chiang Kai-Shek Memorial Hall in Taipei, Taiwan.
During walking around the memorial hall, it got to the time for guard mount. I found three guardsmen climbing up the stairway to the entrance. They wore the same metal helmets and walked everything in perfect order. They were motionless like a robot. The main gate of this site was seen on the other side of them.
Of course, they didn't cast an eye on me who stood beside them. They passed by me as quick as a wink. And they entered into the hall where their colleague waited.
