In the Warring States period, all countries were seeking ways to make themselves stronger. Among them, the Qin State made an important contribution to its own agricultural development and national strength by building the Dujiangyan Irrigation System, a great water conservancy project.

Dujiangyan Irrigation System is a large-scale water conservancy project in ancient China, located in Chengdu, Sichuan Province today. It was initiated and organized by Li Bing and his son, the Shujun Prefect of the Qin State, in 256 BC. The main purpose of this project was to solve the flood problem in the Minjiang River Basin and provide a stable water source for farmland irrigation.

The construction of Dujiangyan Irrigation System demonstrated the foresight and determination of the Qin State. At that time, most countries were busy with wars, but the Qin State invested its energy in infrastructure construction. This vision and decision ultimately contributed to the Qin State's unification of the six states.

In addition, the success of Dujiangyan Irrigation System also benefited from the excellent talent and perseverance of Li Bing and his son. They overcame various difficulties in the design and construction process, and eventually made Dujiangyan Irrigation System a comprehensive water conservancy project integrating flood control, irrigation, and navigation.

Overall, Dujiangyan Irrigation System is a crystallization of the wisdom and strength of the Qin State. Its successful construction not only changed the face of the Sichuan Plain but also laid a solid foundation for the rise of the Qin State.
