What pen is good for practicing regular script calligraphy?

I personally love calligraphy, but I don't think the gap is too big. Pens are more suitable for hard-pen calligraphy copywriting, and pens, gel pens and pencils can all be used for copying. It mainly depends on your intentions and efforts, and at the same time, you should choose the object painted red or copied. Personally, I think it's good to practice some modern hard pen calligraphers' handwriting. If you want to pursue verve, you can copy some ancient rubbings and find restored prints. Personally, I think the copybook effect is not very good, and it should be based on copying. At the same time, when writing at ordinary times, the writing style and feeling of copying should also be substituted. If you get used to it, the words will naturally become beautiful.
