Happy Mathematics in Qiao Hu uses Aesop's fables to teach children to learn mathematics, and of course, our familiar protagonists Qiao Hu and Qiqi lead us to study together. Personally, I think it's very good for Qiao Hu to use Aesop's fables in happy mathematics, so that children can learn mathematics unconsciously in fables. In this regard, Qiao Hu's good idea is really commendable. Whether it is Qiao Hu English Learning Edition, Qiao Hu Pinyin Castle or Qiao Hu learning Chinese characters, these learning resources will not bring any learning pressure to children. On the contrary, they will let children learn knowledge in happiness and cultivate their interest in learning. Perhaps this is the charm of Qiao Hu.
