Mr. Tian Yingzhang's idea is that the correct point needs a pen to go back to the front, but many others on the Internet directly clear it to medium weight.
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.
