People who haven't practiced writing may be blindly speeding up their writing if they want to improve their writing speed. The words written in this way will be ugly and difficult for others to recognize. The most important thing is that your hands will be sour, so it is not a good method.
The improvement of my writing speed is very accidental. I like to practice writing. When I practice calligraphy, I write slowly. When I first came into contact with regular script, it often took more than half an hour to write a piece of square paper. Later, I felt that the speed was too slow to be applied to real life writing, so I began to practice running script.
Buy a copybook and write it bit by bit. It may be slow at first, and it takes a lot of patience to write a word well. But once you practice writing, when you actually need to write, you will write directly because of your feelings, which speeds up your writing.
The second method is to contact dictation ability. This method comes from translation training. Of course, this doesn't mean that you have to write down every word you hear. Generally speaking, you can record important information while others are talking. You must use abbreviations. For example, if I am from Beijing, when I meet the word "Beijing" in what I need to write, I will abbreviate it as BJ. Many other contents can also be abbreviated. When a word or sentence appears repeatedly, I will draw a horizontal line under the sentence and write a word 1 next to it, so that it will save time to replace the sentence directly with 1 next time.
I hope my method can inspire you.
