Personally, I think it is not very good to practice calligraphy with grid, and it is easy to write stiffly. You can try to go back to the palace.
I recommend a book, Huigong Pavilion Hard Pen Calligraphy Course, which is available in Xinhua Bookstore and one in 6.6 yuan. It's also cheap. You only need to buy textbook one. If you don't think it's enough, you can buy textbook 7 or textbook 4 to consolidate your exercises.
Why? The textbook 1, chapter 1, introduces why you use Gong Hui grid in calligraphy practice. After practicing for a few days, I can obviously feel very flexible and easy to use. Even if you write a lot of words, you won't stay. With calligraphy, there is "qi".
The second chapter, from sitting posture, writing, fingering to pen lifting, is a process of pen lifting, writing and pen closing. The process is the same as that of calligraphy. Pay attention to every word, you will find it easy after you get used to it.
The third chapter began to teach you how to write strokes, and solved the problems of horizontal, vertical, skimming, pressing, pointing, lifting, folding and hooking, as well as the matters needing attention when writing.
Then you can learn the key chapter of this book, Chapter 6, at a faster speed, and learn the structure of Chinese characters (single word, left and right structure, up and down structure), which is a method developed by the author of this book, and you will know after reading it.
Textbook 7: Detailed explanation of stroke structure, combined with the application practice of Chinese characters in China.
Textbook 4, workbook.
If you want to be lazy, look at the theories in the first and sixth chapters of the textbook 1 and combine the exercises in the textbook 7. Fifteen minutes a day, I believe that within a month, you can see your progress.
The above is aimed at beginners. If you want to make progress after practicing these, or think the above are simple, you might as well try. It will be more effective to continue studying the third and fourth chapters of the textbook 1 and combine regular script with running script to improve the speed.
I am a teacher who teaches children to write hard pen, but not this textbook. Children can't understand. I think this textbook for adults is economical and practical. You can try.
Now there are some textbooks with loud and big brands. I don't seem to have to learn how to do it. Writing is a technology, and calligraphy is an art. Simply writing words well can achieve results in a short time, but it can't be done in three to five days, and it needs a continuous and repeated process.
I hope you can write down your words as soon as possible.
