The rat tail produced in Northeast China is the most common wolf hair, which is called "Northern Wolf Hair" and "Kanto Liao Wei". Wolf hair is stronger than wool pen, and it is suitable for writing and drawing. Wolf hair is actually the "hair" of the weasel. Weasels can only use the tip of their tails as pens. They are tough by nature, second only to rabbits but too woolly, and they are also healthy pens.
Wool is made from the hair or tail hair of green sheep or antelope. Calligraphy is the most important thing, sheep are soft and have no front, and books are "weak and boneless", which are rarely used by calligraphers in past dynasties. After the Southern Song Dynasty, Yang Hao began to make pens, but after the early Qing Dynasty, pens were widely used. Because the Qing Dynasty paid attention to roundness and delicacy and was not allowed to show off talents, only soft wool could meet the requirements and was widely used at that time.
