he order of the evolution of human thinking is from concrete to abstract, from graphics to language. Anyone who has a rough understanding of the history of cultural relics knows that there are only graphics on early civilizations and their artifacts, such as prehistoric murals from all over the world, such as fish patterns on Banpo pottery, faces, and so on. There is no writing, because the language ability is underdeveloped. After the language ability is developed, there will be words, and human civilization will really break away from the primitive stage. The evolution of characters itself follows the same process. At first, it is graphics, without taking off representations, and its coverage is very limited. It slowly leaves the graphic stage and really becomes words, indicating that people's language ability is getting deeper and deeper, and their thinking is becoming more and more independent.
