Hi and welcome to the Forum.
Your forum information tells me you are a citizen of Hong Kong. If you hold a UK passport with the right to live and work in the UK, then it's possible. However, if you don't, it will be extremely difficult, if not impossible to get a work visa. You can get more information about British National (Overseas) passports and visas from the UK Gov website; this will take you straight to it.
We have a jobs section on this website (top of this page), just check it out, perhaps there is something that interests you.
Long-distance job searching is always problematic. is as good as any online recruitment agency (there are many), try there.
I hope this helps.
