In ancient times, we should read more famous articles in textbooks, such as "Please Wu Zhao", "Epang Palace Fu" and "Touching the Dragon to Meet Empress Zhao Xian".
In the process of reading, we should understand the author's writing techniques, know more about the use of allusions and structures, and write a few sentences or a paragraph of notes after reading. This is for yourself. You can write at will, even if you copy a few sentences that you think are good. It won't be long before your writing level can be improved to a great level.
The above methods are the fastest way to improve the level of argumentative writing that I have summarized. Of course, there is no fixed pattern in writing, and there is no fixed distinction between good and bad. The so-called literature has no first, and martial arts has no second; The improvement of writing level should be compensated by an objective attitude. You have to be satisfied with what you have written before you show it to others. Don't write for a task, leave something for the history of words. Only with this mentality can we write good things.
