have to teach her chinese words

I am thinking to teach my children Chinese words. I have no idea how to start until a customer teach me the skill. She is a teacher and have been using the same skill to teach her 6 years old children since little. Her daughter already upgrade to Primary School standard 3 at the age of 6!

I do not wish to have a daughter like her but I do wish my daughter knows how to read Chinese word and master Chinese words as well. I will try the method and see if it suitable for my daughter.
