welcome to HK, I am sure you will like our beloved city, highly efficient, clean, and safe to wander around late at night.That sounds like a good plan achieve some seniority in your occupation. While It's true Europe will stagnate and I'm of the opinion it already had a lost decade since 2008. It's still a good place to be, but it's so boring in western Europe it feels like we can only look into the past because the future looks kind of meh there's no big European dream/project or something.
That is one the reason I'm leaving next year I will most likely go and try to find a job in Hong Kong or shenzhen and will leave for at least 4 to 6 years. If I like Hong Kong enough, I heard you can get permanent residency after 7 years..Maybe I will go for Hong Kong permanent residency. Also better pay as a software engineer looking at glass door and LinkedIn posts and also lower taxes.
prices here are alright, except for housing which can be very expensive, cheers.
