If it is a pen, you can use an ordinary magic pen, which should be available in bookstores or supermarkets. 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 expressive force and artistic appeal of the pen are not as rich as those of the brush calligraphy, they are far superior to other hard pens such as pencils and ballpoint pens, because the nib is elastic and the strokes written are the same. A beautiful brushwork can also give people beautiful enjoyment. Especially in recent years, with the popularization and improvement of pen calligraphy teaching, the vast number of pen calligraphy educators and enthusiasts have made beneficial explorations and attempts on the brushwork, structure, composition and style of pen calligraphy in teaching and writing practice, and created many excellent pen calligraphy works with five styles: open, closed, grass, official and printed. These works have the beauty of form, expression, charm, artistic conception and momentum, forming a sense of beauty with rigorous structure, echoing strokes and smooth bones, enhancing the appeal of pen calligraphy art and being widely praised by the society, making pen calligraphy a big step from simple practicality to artistic style.
