1, avoid colloquial words. I believe that writing colloquial words is a habit of many people, and sometimes we don't even notice it when it's finished.

2. Make clear the internal logic before writing, that is, clear your mind first.

3. Sketching point by point, relying solely on the deduction of the brain, thinking is still easy to be confused, especially when thinking about complex problems. We can write down the logic program.
