It is recommended to practice 1 to 3 months of regular script foundation first. Find an interesting font from Ou, Yan, Liu and Zhao to copy.
After a certain foundation. You can find a font that interests you. Which choice and research do the real grass Wei Lixing like? Find some famous posts, such as cursive script, study Zhang Xu, Huai Su and other posts to learn and practice. If possible, you can find a calligraphy teacher to listen to and be taught. Don't go to any calligraphy training class for the elderly. As far as I know, the people trained by these institutions are exactly the same. Limited thinking, meaningless. The most important thing is to create more calligraphy. Don't worry about novice handwriting. Create it, hang it up and ask for other people's advice. It is of great help to improve. In addition, for beginners who choose writing brushes, they can choose longer and harder pens such as medium and long peaks. I hope it helps you. Wish you good health.
