Just came back from a 2 weeks multi-city vacation in China. Walk around with a backback carrying a camera & 4 lenses. Setup tripod in the middle of the city square and Bell Tower roundabout in Xian at 10+pm for night photography alone. Place was still crowded and happening but no one even bat an eyelid or hassle you. It's the same in the other major cities.
China is actually is a lot safer than most other advance first world countries where you wouldn't even want to be out alone at night.
