any kids attending 2 kindergartens

I wish my son can study in local kinder to learn better Chinese, however we can't accept the stressful school life of local primary school, plus that 國民教育subject in the future is really scary!! that's why we have chosen the ESF kinder in order to get a better chance for ESF primary school.
other than the ESF kinder, I am planning for my son to attend a local kinder for 2 afternoon a week to learn better Chinese, is there any parents doing the same?
