The term slave society was moved to China according to Marx's five social forms. Ma Lao-Ren said that social development must go through five forms, so social theorists in China followed the map and saw that Oracle Bone Inscriptions and the bronze inscriptions of Shang Dynasty all recorded the use of slaves, and there were many martyrs in the tombs of Shang Dynasty, so Zhou was designated as a slave society and later Qin and Han Dynasties as a feudal society. . . But Marx himself admitted that he didn't know much about the history of Asia, so he created the concept of Asian mode of production, that is to say, five social forms may not be suitable for the history of China. It is generally believed that slaves did exist in Xia, Shang and Zhou Dynasties, but the mode of slave production in western history did not appear, because slave owners were domestic slaves and did not put into production in large quantities, and the number was not large. So strictly speaking, slaves in China are completely different from those in the West. What's more, domestic slaves still existed throughout ancient China and even during the Republic of China. Therefore, some people think that if there are no slaves in the Shang and Zhou Dynasties, it can be called a slave society. China's social form has its own characteristics, which cannot be explained clearly by western historical theories.
