Chinese dynasties from different time periods established different social structures based on factors like class, gender, and social mobility. The dynasties from the Classical Era, Post-Classical Era, and Early Modern Period each defined social structure in their own way while also maintaining some consistencies between eras. Specifically, the Ming and Qing dynasties from the Post-Classical Era shared similarities in social structure with the Song and Tang dynasties from the Early Modern Period based on class, gender, and social mobility.
