So, I guess you counter Wikipedia then to stress your argument. Whether he started in 2004 or 2001, does it matter to you? What's important is he finished it.
Uuuw added: I don’t see a point arguing about this but I just found it ridiculous....even the original Wikipedia page didn’t say anything about his enrolment was in 2004, and he mentioned several times in his previous interviews that his dad required him to enrol in ChungAng uni as a prerequisite to be an actor. That is before his debut.
Wikipedia - Hyun Bin - Personal Life. You will see 2004. It's there dear.
