Yes, the Song Dynasty in ancient China did have some degree of social mobility. This was partly due to the civil service examination system, which allowed talented individuals from lower social classes to rise through the ranks and obtain government positions based on their merit and knowledge. Additionally, economic growth during the Song Dynasty created new opportunities for social mobility, such as through commerce and trade. However, the social mobility was still limited to a certain extent, as the upper classes still held more power and privilege. Overall, while there was some social mobility during the Song Dynasty, it was not completely unrestricted.
