Xu Rong said in Biography: "The way of seal cutting is grammar, composition, brushwork and knife cutting ... The seal of each dynasty should be the main body of each dynasty. Do not mix its text and change its seal. " Shen Ye also showed the importance of knife method, composition method and word method in seal cutting creation in Yin Tan. It can be seen that seal cutting, composition and knife cutting are closely related and inseparable in seal cutting creation, which can be called the three elements of seal cutting creation.
To learn seal cutting, you must first learn seal cutting. The method of printing emphasizes seal cutting at first. To write a good seal script is to master the unique structure and lines of seal script, and to master the ability to perfectly shape this kind of writing symbol, that is, to solve the problem of seal script. At this point, everyone should understand that learning seal cutting requires writing a good seal script. Mastering seal cutting requires extensive knowledge, and you can't make words by sketching on the side. Therefore, Zhu Jian said in "Sealing Classics": "Learning has no foundation, and it is also ill if it is compiled on the side." Usually, learning seal script is based on Shuowen, but it is not bad to pass Shuowen. Between square inches, in a tiny place, there are probably four kinds of seal characters: long, short, wide and narrow, which are surrounded by paper. If you try to seal script, you can increase it if you can, and save it if you can. For example, the changes of ancient seal characters are different, such as adding pictures, reducing strokes, borrowing and merging, and shifting tones. As we all know, the seal cutting method is ancient and unique, but don't lose the ancient method because of ingenuity. For example, Zhao not only used ancient inscriptions, but also extended the reference scope to coins, imperial edicts, Han lanterns, Han mirrors, Han bricks, clay seals in the Warring States period, as well as inscriptions in the Wei, Jin, Southern and Northern Dynasties. They are all eclectic and comprehensive. For example, "Income after the Tongzhi Era of Shen Shuyong" is a method of worshipping the Sangong Mountain Monument; "Lingshou Flower Pavilion" is a way to open a ramp and carve it on the cliff. On the other hand, based on Zhao's achievements and casting, the printing is very coordinated and has made a big step forward.
