Written, of course. I studied calligraphy. I was the deputy head of the Art Troupe of our College of Humanities in college. Hey, hey, for an example, when we made posters in college, the most commonly used pen was the big-headed pen, that is, a pen with a thick head and a thin head. I don't know if you have used it, but you can buy it and try it. The head of that pen is a plaque, which is thick when written horizontally and thin when written vertically. Here is the word I wrote, you can refer to it, hehe.
