I have my boy in Lingnan nursery which starts for kids at age 2 yrs old. So far, they are doing quite fine in discipling my active boy and he can sit still to listen to stories. I can ggod improvement in him but of course boys are boys....
They uses cantonese to teach. As far as I heard, their motto is "happy children" so kids have not much stress there and are relatively happy.
Many will continue with Lingnan until the Kindy stage where they will explore other primary schools.
