Zhenhai has a population of about 250,000(ish) but there are very few foreigners here. When the local government set up the "foreign experts club" (for the foreigners allowed to work in the city) there were 50 members or so members, tops.
I say all this because I went for a walk along the sea wall today, and had my photo taken 5 times. Now I wish it was because of my Adonis like appearance, or my sparkling intellect, but I bet it was just because I was foreign.
