When children reach kindergarten age, parents will send them to kindergarten to start their education. You definitely need a notebook to go to school, but parents don't know what notebook the kindergarten uses to write Chinese characters. Let me tell you something about it. Kindergartens use Tian-zi grids to write Chinese characters, so that children can write in a standardized way. From the beginning, children's fonts will be more neat in the future. Although there are only four small squares in Tian Zige, in fact, each one has many patterns. Every line, every grid and every position in the grid has its own different name. Memorizing Tian Zige and remembering the names of each part is an important prerequisite for learning to write. After understanding "Tian Zige", we can appreciate Tian Zige's Chinese characters. It is an important link for children to feel that every word has its place and cannot be put casually. Only by gradually standardizing Tian Zige's Chinese characters can we lay a solid foundation for future Chinese learning. Kindergartens write Chinese characters in grid books, so that children can write regularly when practicing Chinese characters, which is helpful for children's future font neatness and lays a solid foundation for future Chinese learning.
