For chinese parents, would u send ur child to english or chinese enrichment class first and why?

i send my elder gal for chinese enrichment as she refuse to speak mandarin. she is stronger in english so i never bring her for any classes. she went for tien hsia when she was 3.5yo. it was amazing that she learn a lot from there. its more like a speech and drama class to me as they do performance every end term. it help to build up her confidence in front of the audience. now she is already in k2, her chinese seem better.
