It is more appropriate for children to start learning hard pen calligraphy at the age of 6. Because the hand muscles of children under 6 years old are not well developed and the wrist strength is not enough, hard pen calligraphy needs a high degree of coordination and precise strength control. If children are allowed to practice hard pen calligraphy too early, they will feel frustrated because they can't grasp the pen. In addition, children under the age of 6 can't concentrate for too short a time, and it is easy for them to get bored by practicing calligraphy for a long time.
Hard pen calligraphy is divided into hard pen calligraphy art and practical hard pen calligraphy. The former mainly emphasizes artistry, while the latter mainly emphasizes practicality. The artistry of hard-pen calligraphy mainly expresses the writer's understanding and feeling of calligraphy art through the changes of lines and structures. It pursues beauty, affection, interest, artistic conception, personality, etc. Practical hard pen calligraphy, that is, daily writing, is mainly to meet the needs of practicality and facilitate writing and identification. The key is to make the writing fast and standardized, so the practical hard pen calligraphy is mainly running script.
