The benefits of children learning calligraphy are as follows:
1, learning calligraphy can calm children down, nourish their spirits and benefit their physical and mental health. In the process of learning calligraphy, children mainly practice, especially training the movements of fingers, wrists and arms to achieve coordination and flexibility. These movements are directed by the brain, and regular training is beneficial to the growth and development of the brain. Primary school students are in the golden age of brain development, and it is very necessary to practice calligraphy in this period to promote children's brain growth and development.
2. Calligraphy can cultivate students' good moral sentiments. Calligraphy is the quintessence of the Chinese nation. There is a long history of development from the initial formation of characters to the improvement of calligraphy art. In this long river of language and characters, there have been many great calligraphers of different dynasties and generations with different styles and excellent personalities and knowledge. Whether they are diligent and eager to learn, or their principles of being a man, they are all examples for us to learn.
3. Calligraphy can improve people's comprehensive ability. Let's assume that two people have the same education and the same job. But one of them has practiced calligraphy, and the other has never practiced calligraphy. Probably, the former thinks and handles things in a higher angle, method, vision and realm than the latter. He can look at and handle things with an artistic eye, and he is likely to achieve greater success.
