I flew from the airport in question to Shanghai a couple of months ago.

Security wasn't unpleasant, but it took a while, there was a long and slow moving line. We had to discard lighters and show passports, but the latter is par for the course in China. It feels like the Chinese are slightly more overbearing with foreigners, which helps, since there's a huge language barrier.

We where lugging a flight case of cymbals, which got quite a lot of attention and laughter from the operators going through the x-ray.
