In this composition, you have divided the most important factors into different situations. At the end of the article, you have added an extra factor different from the ones given in the question.

I am a little confused, since the main question is the most important one of the three factors, is this end of the article a little off topic (domestic education is to sum up the previous points)? In other words, to what extent does my article clearly express my opinion? Because I feel that the structure and content of your articles are more readable and flexible, compared with the articles given by various online resources,  I would like to learn from you. But I really can’t understand why you deal with the article like this, so I would like to consult you. I hope I didn’t disturb you, thank you!
