Well it depends on which area you are specialised in... For most PhDs they are "做" rather than "讀", because it is a degree by RESEARCH rather than a TAUGHT degree (i.e. no or very few lessons and/or exams, and whether you can pass or not depends on your thesis (論文)).
There are 2 ways to do a PhD:
1. Design your own project and present it to a member of staff/dept of a university (you will have to pay for your own fee). If they think its ok then you start your PhD there.
2. Apply for fundings that are advertised by e.g. industries, goverment etc. In this case you will be kind of like working as a Research Assistant (and get paid) but at the same time work your way towards a PhD.
Both ways are possible, i suggest you to speak with your tutor if you are interested.
Usually it takes between 3-5yrs full time, again depends on your performance.
With a Masters degree is of course a benefit, and it also gives you some understanding of how researches are being done. Unless your undergrad performance was very good, pple with a Masters degree will have some advantage over you.
Hope this helps :)
PS. i am an UK PhD graduate, so things may differ a little bit in HK... again, speak to your tutor and express your interests, good luck!
