Where can I maximise my earnings?

High school student here with an offer from the LSE for Bsc finance. I know LSE is a top target for getting into london finance jobs but thinking in the long term the salaries & take home pay in london is pretty sorry compared to other cities abroad.

What would be the best place for me to earn the most in the LR provided I’m an southeast asian citizen with intermediate-advanced mandarin and native english? I’m considering HK and SG, would it be better to endure a few years in london on low pay and then move to asia or maybe try US or other cities?
