In terms of children's cognitive development, reading ability opens the door to another world for children. Compared with the real world, reading can provide children with a world full of countless magical and possible imaginations and fantasies, thus promoting students' thinking and understanding the richness and diversity of the world. However, the premise of autonomous reading is literacy, so literacy teaching has been paid more and more attention.

Moreover, with the progress of science and technology, the teaching of modern Chinese characters in preschool education is no longer as rigid as before. In this era of multimedia application blowout, a number of preschool education platforms headed by "Mao Xiaoshuai learns Chinese characters" have successfully replaced the old literacy cards and point readers, creating very favorable basic conditions for modern literacy teaching.
