I think it's good. I have learned all kinds of knowledge, such as literacy, arithmetic, ancient poems, children's songs, daily knowledge and so on. The program is well arranged to teach children how to protect themselves, and there are different teaching materials and toys for each age group.
You can buy a CD and show it to the children first. If the child likes it, buy the genuine one. If the children don't like it, the money will be wasted.
There are also online, Baidu "Qiao Hu", let the baby try it first. I like to book again.
