ash, i don know wad u mean by mixing english and chinese language in class. Cos the english teacher is indonesian, basically she only know and understand english. Not those professional english style la. Still acceptable. There will be a chinese teacher in the class, for wad i understand, this english teacher explain to me that because some children don understand english(maybe they only speak chinese at home?), so the chinese teacher will speak and explain to the children, she never speak very loudly like the english teacher conduct the class, but if the kid run away she will just walk over to the kid tell him to come back and sit down. Actually most of they speak english la. I feel that is bad for the chinese teacher. Cos i think she don really understand english. lol!
