In your case, you can still apply for teaching (but finance is a hot major in Hong Kong). Personally, I think a second degree is still useful, but it is not recognized in Hong Kong. Secondly, I think it is very useful for you to practice in financial institutions such as banks. The above two points can help you apply for a master of teaching. The research style is still not enough unless you can send international papers. How to prove that you are better than other majors if you don't send papers across majors? But this kind of international paper is difficult to publish. How many financial teachers in Jida can send?
