my preference : Think
my daughter is now studying their K1 (promoted from their N1)
have nice and caring teachers
creative teaching methods and activities
focus in Cantonese in N1 (provide a good foundation of our mother language) plus learning Eng + Putonghua
more focus on Eng + Putonghua from K1 onwards
highly focus on languges and writing skills esp. in upper classes
most important is, my daughter is studying happily there
