White people stick out in China. There's no way around that. The taller you are, the more you stick out - or up, actually. While I am not tall, at 5 foot 6 1/2 inches I was easily a few inches above most crowds on the street.
Makes you feel just a little conspicuous.
That, and having everyone giggle as you walk by. And take your picture.
I have a little more empathy for paparazzi-chased stars.
My retaliation? Take their pictures right back.
