When the dry character counts from one to ten, it is a ten, that is, "ten", which is written vertically according to the traditional writing method, that is, the origin and development of the dry character.

"Gan" is a hieroglyphic, which first appeared in Oracle Bone Inscriptions in Shang Dynasty. Oracle Bone Inscriptions's word "dry" looks like a shield at the top, like a handle vertically, and like a shield horizontally. There are three kinds of bronze inscriptions. The first one is inherited from Wen Jia, which is obvious. In the second case, the horizontal painting is changed to dotted filling, which is the common practice of inscriptions on bronze; In the third case, the shielding surface is represented by one shape, and the rest are the same as other shapes. The two examples of Warring States script basically inherited the form of A and inscriptions on bronze, but the form changed slightly. Seal script inherits the shape of bronze inscriptions, which looks like a shield at the top, a horizontal handle and a handle at the bottom. It is not easy to understand when you translate the words into official script and then change them into regular script. The above shapes are all made according to the specific image. It belongs to pictograph in six books. Now the unified standard is simplified to "dry".
