Okie I think there is a lapse in the definition of “Chinese oriented schools” between you and I. You are talking about origins and history, I’m talking about whether the schools place huge emphasis on promoting the Chinese language in their curriculums and activities.
Over the years, many old schools were closed, many new schools were opened. Those schools you mentioned don’t represent a majority now. I have friends with kids in those schools you mentioned, don’t find them to be particularly Chinese focused.
but well of course I do know one or two among such schools which are somehow favoured by parents from a certain nationality… Inevitably their kids will be chatting away in Chinese and their number can sometimes be quite significant
