I don't know, most professionals in HK I have met are pretty open to challenging people but maybe that's just the people I choose to work with.
In any case what I find strange is that usually HK finance companies (like much of the rest of the world) will have some kind of maker-checker system which prevents individual mistakes like this.
I met 3 top managers from China (talking about very high-level managers) to whom I had to talk to and were kinda more challenging and open than the other Chinese I had to work with, but nowhere near the Germans, Americans or Italians.
