I don't follow much about the "Secretaries" in Hong Kong, so I was looking at wikipedia to learn more about Kevin Yeung. I was specifically wondering where he got his EdD or PhD in Education from... but then I saw he didn't have, so then I wondered about his Master's in Education... nope... Bachelors? Nope.
How could it possibly be that the Secretary for Education doesn't have any education background in education? Would you have a Secretary for Justice that is not a trained solicitor? Having a look at the history of the Secretaries of Education, it seems they never come from backgrounds in education. I guess it's just a shoe-shiner position?
(Seems it might be a position for characters with dubious records...)
