Prior to 2020 there were quite a few people who still lived blissfully ignorant, but even before that COS18 SOs were only here for rating, time and then a departure to something more sustainable. This is not just 'westerners' either; CX isn't appealing to those who are 'local' either. Aviation is no longer a safe choice of career in the city.
I don't know a single pilot who intends to stay here medium or long term including local HK pilots/cadets.
