Was just there last week.
I wore my full chasidish garb, and no one even blinked an eye. Traveled on airplanes, trains, metro, all over, never felt unsafe. The only issue I had was, NOBODY speaks your language. One person told me I look like a hipster and if I was muslim........Chabad of SZX prepared a great meal, and we also had a great meal at JCC in HKG.
