Macroscopically, the Warring States script can be divided into two systems: Six-country script and Qin script. "Six-nation script" refers to the scripts of six countries, including North Korea, Zhao, Wei, Qi, Chu and Yan, and small countries such as Zhongshan, Yue and Teng. Compared with bronze inscriptions, the most obvious features are the random simplification of strokes and the extremely chaotic physical structure. Qin Shu is close to the orthodox inscriptions in the Western Zhou Dynasty and the Spring and Autumn Period, and it is more rigorous and unified. Later people called it "Shu Shu" or "Da zhuan". Due to the "different writing styles" in different countries and regions, the writing style of the same word in the Warring States period was greatly confused.
