We are now interviewing pilots with 8,000 hours jet experience for First Officer positions on the freighter aircraft, B747 and B747-400. So I guess that is not your expected path.
For S/O positions the first thing you need is
PR in HKG. After that you need enthusiasm, education and capability. You are not too old to apply, and gliding shows that you are interested in aviation.
If you have the above, why not send your CV to CX recruiting? No one ever got hired who didn't...
And like the Air Force recruiter said to me years ago, "If you have to ask me who to call, perhaps you do not have the initiative to join."
Best of luck
