Taking Baishan wool as raw material, the varieties and specifications of goat wool are strictly divided. It should be carefully selected and matched according to different producing areas, seasons and age groups, as well as the grade, thickness, softness and length of leading edge of different parts of sheep. Nowadays, many people call a pen with long hair a long leading edge pen. In fact, a pen with a long leading edge is a long leading edge pen (also called a deep leading edge pen).
A pen with a long nib can only be called a long brush or a long brush. The price difference of Baishan wool is very big, and the real long-front and deep-front wool pens are not cheap.

Appreciating a calligraphy work, different people have different angles. The author thinks that we can grasp the key from two aspects: modeling and temperament. We can also divide the form and quality of calligraphy works into material level and spiritual level.
Judging from the classic works in the history of China's calligraphy, there are many changes in form and quality, and there are also many kinds of air patterns. Although shape and air lines are closely related, they are not in one-to-one correspondence, and often have different arrangements and combinations. Therefore, in theory, the art of calligraphy can form countless styles. Mr. Qi Gong's calligraphy can be summarized by "Qing" and "Ya".
Careful examination of each of Mr. Qi Gong's calligraphy works, whether it is a real book, a running script or a cursive script, whether it is large or small, can achieve clear eyes and clear strokes without any entanglement and ambiguity. This is the basic expression of what we call "Qing", which is easy for most viewers to feel and need not be repeated.
Formal "purity" can give people different feelings, such as rigidity, fierceness and even decadence. Of course, this is related to the different treatments of brushwork, writing and composition. On the other hand, Mr. Qi Gong's calligraphy conveys an elegant and elegant feeling to us through "Qing". The combination of "purity" and "elegance" constitutes the overall style of Mr. Qi Gong's calligraphy.
