gardenwoods,
我心儀既都係合一堂 (my friend who is working at an international kindy and her principal (who also is the chairman of the HK kindy association in HK) highly recommend this one for me (in MOS area).
My friend knows kindy in HK pretty well and she was reported by different magazines and TV occasionally. So, I guess the opinions she gives me are pretty worthy.
I put my kids to Lang Liang at MOS mainly is because this kindy are famous for caring the kids (很有愛心). My kids are very happy at this kindy and they love the kindy life so much. They also can sing a few Chinese songs although they didn't know any 2 months ago. teachers are excellent at this kindy.
I think I would love to choose 合一堂 for Luc if we are still living at this area cos' it is closer to our house compared to Lang Liang. But both are highly recommended.
