Did Qin shihuangdi's strategy of conquest help or hurt china?

Qin Shihuangdi's strategy of conquest helped unify China, bringing an end to the Warring States period and establishing a centralized imperial government. This unification facilitated infrastructure development, such as the construction of roads and the Great Wall, which enhanced trade and security. However, his oppressive methods, including harsh laws and forced labor, led to widespread suffering and dissent, ultimately contributing to the dynasty's rapid collapse after his death. Thus, while his conquests laid the foundation for a unified China, they also sowed the seeds of future turmoil.
