Just glanced at the thread out of curiosity, I do not have personal experience with China
I do have a buddy that is flying there though and has a couple of tattoos so I am not sure about this "very unfavorable" remark, as well as the full body strip down search. Its hard to believe that they ask 40-50 year old pilots to take their underwear off to check them, for what?!?!?! Do they ask them to bend over to check for prostate too?
Even harder to believe that they actually do
Anyway, never heard of it from anyone but doesn't mean its not true.
I am sure some other members will tell us if it is just another urban(chinese) myth.
Funny though
I do agree with Wyo on mentioning it
