As long as A3 paper is suitable for hard pen writing, everyone's writing habits are different. It is not recommended to buy this kind of paper online. Stationery stores can buy it. For the writing of middle school students, if you want to write regular script, running script and official script neatly, you must mark or draw lines for reference. Suggest marking or drawing lines by yourself. I think it is more important than writing:
1. By marking or drawing lines, you can warm up and calm down before writing.
2. Placement or drawing lines need to know what is written, how much is there, and how many boxes need to be typed. This process is also a further understanding of the writing content.
3. Before typing and drawing lines, you should think about how to write the text and how to write the inscription. You should consider the elements of calligraphy from beginning to end, such as composition and layout. When you finish typing, your sense of accomplishment will naturally appear, and then you can write your work with twice the result with half the effort.
