The quality requirements put forward by the Ministry of Education for normal students are also one of the basic vocational skills that students must possess. As a writing tool for Chinese characters, pen has the advantages of small size, convenient carrying, convenient writing and durability, and the written characters are not easy to fade. From an aesthetic point of view, although the line expression and artistic appeal of pen characters are not as rich as brush calligraphy, they are far better than other hard pens such as pencils and ballpoint pens, because the nib is elastic and the strokes written are the same thickness. Brush writing refers to words written according to traditional statutes, rather than words written casually with a brush. Calligraphy is a line modeling art, and the so-called brush strokes mainly talk about how to shape ideal lines. Chalk characters refer to characters written in chalk made of calcium carbonate, calcium sulfate and a small amount of calcium oxide.
