The mainland isn’t tough. You do as you’re told. There’s a couple of quirks to it, but I can happily report that all of my former KA colleagues found it fairly straightforward.
You would have to be some sort of useful idiot to believe that, terrain, weather, ATC speaking in Mandarin or level 3 English, metres and/or QFE, crap controlling with multiple runway changes in the last 50 miles. Straightforward? Sure I guess if you were one of the crew of the Apollo 13 it may seem that way.
Of course after operating in that environment 150 times a year you get comfortable (or worse complacent) but it's anything other than straightforward. I believe IOSA would back me up on that
