China's administrative frameworks during the Tang and Song dynasties showcased centralization and bureaucracy. The Tang dynasty employed a tripartite governmental structure and a ranking system with nine levels for officials. Similarly, the Song dynasty had three divisions and introduced a civil service examination system based on meritocracy. This distinctive approach enabled individuals to vie for governmental roles based on their aptitude and expertise. While both dynasties displayed centralization and bureaucracy, the Song dynasty's eminence stemmed from its merit-based system, which differentiated it and bolstered its achievements.
