Do you need to study fine arts to study calligraphy? What are sketches and sketches?

Hehe, I was born in fine arts. Calligraphy is not necessary. I practiced calligraphy every day before I studied fine arts, and now my calligraphy is not bad. I often participated in some calligraphy competitions during my college years. I suggest that I learn calligraphy better from primary school, but it will be better to have a foundation of sketching and sketching. After all, calligraphy is also a combination of points, lines and surfaces.
