my son studied there last year and changed to PN class in another KG. Teachers there are ok if you're just looking for "nursery" service. I quit when my son reaches 2 so I don't know their academic level. But definitely, there is no NET nor PTH teachers. And also, the 副主任 is not very nice and not experienced.
As long as teachers are caring and loving, it is ok because we live nearby. We do not need 托兒服務 but we want him to study in a chinese and creative environment.
