ESF Tsing Yi - level of Chinese taught

We are happy to receive ESF offer today. We love the school's curriculum and priority to their primary schools, but the only downside is v little Chinese taught. We believe Chinese is also important and thinking if it can be supplemented by private tutor and not certain whether it'll be effective.

Can existing parents of ESF or other international schools share your views, your child's level in writing and reading Chinese, and your experience in whether private tutor to learn Chinese has been an effective option or any other option

Many many thanks
