It is glad to hear somebody interested in psychology. I think there is no need to study at Asian countries since you are doing well at the UK. As soon as you find a master program that fits your area and goal, you can take it; even though there are two main things that may help your selection.
First : Academic requirement of the master program (at least a B average but also depends on the university.
Second : sensitive to developmental psychology (normally child psyc today refers to developmental psyc, you may find a master program or course based on the term "child"; but in general, developmental psyc includes what you looking for.
You can base on your academic performance to select your university, not necessary the best school but maybe a university within 400 of the ranking system. HK accepts psychologist from Australia, UK, US and Canada for registration, this is for people who has at least a master degree, therefore you have many choices; it is not a bad idea to ask early.
