What are the characteristics of traditional Chinese characters in pre-Qin period?

The progress of civilization and the development of commodity exchange in the Warring States period promoted the increasingly frequent and extensive application of characters. Pre-Qin traditional Chinese characters developed along the two poles of aristocratization and popularization. Noble fonts are neat and often used for inscriptions on ritual vessels; Civilians scribbled, mostly used in seal script, money and pottery, showing a simple and quick aristocratic whole character, which became the origin of seal script later; The popular cursive script is called "cursive script" or "ancient power", which became the origin of official script later.
