Since the Yuan Dynasty, the "Hu Bi" produced in Shanlian Town, Huzhou City, Zhejiang Province has become the most famous brush variety in China with its characteristics of "sharp, neat, round and healthy". Brush has different names in past dynasties. During the Spring and Autumn Period and the Warring States Period, the vassals dominated. At this time, countries have different names for writing brushes.
Wu (now Jiangsu) called it "illegal" and Chu (now Hubei) called it "bamboo". After Qin Shihuang unified China, they were all called "writing brushes". Bai Juyi called the pen a "millicone", and the poem "Send Micro" said: "The eyes are like the tip of a cone."
Extended data:
Writing depends on the generation of writing brush. The research shows that the writing brush was produced in the Neolithic Age in China, and people in China have used it for thousands of years. Paintings and patterns on painted pottery should be painted on the embryo with brush strokes.
Oracle Bone Inscriptions should also write with a brush first, and then carve with sharp tools. However, the earliest brush was found in the Chu tomb in the middle of the Warring States period about 2,500 years ago.
The earliest tombs where brushes were found were the Chu Tomb of Changtaiguan 1 in Xinyang, Henan Province and the Chu Tomb of Zuojiagongshan in Changsha, Hunan Province. Its unearthed brush is similar to the common brush today, but the pen holder is slender and the nib is 2.5 cm, which is slightly longer than the nib of modern low-profile brush.
