Flash Cards. Learn writing, and Mandarin.
I do not think that one should try to be Chinese as I do not think that that can be defined. But if there is this skill of a language at home, it is not certain that it will be learned. Schooling invariably takes over. Sorry for those lovely teachers. But a great teacher would allow a child to see what is around them as an environment for learning. My children have not learned the various dialects that were available for them. They are not alone in this. But how do you start? Some structure would be handy, and these flash cards are lovely to hold, and they have a lovely brightness to them. Their pictures are attractive and related to everyday activities. The back has pronunciations and calligraphy. There is a tactile love here, and a relationship need. Electronic devices would be the lonely alternative to this.
