Of course, it is best to practice hard pen calligraphy in childhood, which will be of great help. In terms of time, children can spend a lot of time practicing, which is of great help to the standardization and beauty of their own fonts, and will also have great exercise for their minds and cultivate their self-cultivation. In particular, it is of great help to exercise patience and beautify fonts and practice other fonts in the future.
It will be difficult for adults to practice hard pen calligraphy, because after years of education, the fonts of adults have been fully formed, while the fonts of children have not yet been formed. Therefore, adults need to change fonts, and need more energy and time for later practice. Once the once effective hard pen calligraphy is put down, it is likely to be "returned to its original shape". So adults need to keep practicing.
Hard-pen calligraphy is a traditional culture in China. I want to practice all night, but I can't practice intermittently. You need to keep practicing, so you can't stop practicing for a long time. If you stop, you may not get it back. Therefore, if you want to practice a good hand, you need not only enthusiasm, but also great patience and perseverance, which has a great influence on one's mind.
