I am not sure wor! My purpose going there is for child's assessments particularly refered by the assessment centre in Kwun Tong. They are doing some research on my child's genes (whatever, i am not sure) in attempt to find out if there are structural factor that accounts for her late development. (But I have heard from some other parents it doesn't have any findings after all and thus not necessary to go at all.) Its jsut a waste of time but my C6 insists to go. Doing it is just to please my C6's wish.
