Fair enough. It is such a different mindset in Hong Kong... here preschool is something you do if your kid is behind developmentally, or both parents need to work.
Are the local kindergardens as strict & homework-heavy as the local primary schools? If so, I do not want my son in that environment. Children should enjoy learning - not be beaten down & broken by it. Ideally I would put him in a combo of Mini Mandarins (a commute, but I love what they do) & Montessori.
