List 3 actions that the Emperor of Qin took that helped China:

1. **Unification of the Warring States** The Emperor Qin, known as Qin Shi Huang, conquered rival states and unified them into one centralized empire around \(221\,\text{BC}\). This consolidation ended centuries of warfare, creating a single political structure that laid the groundwork for the development of modern China. 2. **Standardization of Systems** To promote cohesion and efficient governance, he standardized various systems across the empire. This included a uniform system of weights and measures, coinage, and even written script. The standardization helped facilitate trade, communication, and administration throughout the vast territory. 3. **Infrastructure and Legal Reforms** The Emperor initiated major infrastructure projects such as the early construction efforts related to what would later become the Great Wall, along with extensive networks of roads and canals that improved connectivity and defense. He also instituted legal reforms to centralize and standardize laws, thereby strengthening governmental control and promoting stability across the empire.
