The historically famous Emperor Qin Shihuang was an emperor who unified six vassal states. Accordingly, China became a powerful empire with a large territory. After unifying the country, Qin Shihuang implemented a number of measures to make China more powerful and richer. Among these, Tan Thuy Hoang has achieved great achievements in the construction of the road system for convenient transportation and development of trade. Specifically, King Qin ordered the construction of many large roads spreading throughout the territory of China and taking the capital capital Ham Duong as the center. Accordingly, many major routes radiate from Ham Duong in different directions to remote areas of the country. These roads were built under the reign of Tan Thuy Hoang and are large in size so that many vehicles can pass through at the same time. Some studies by experts show that Tan Thuy Hoang built about 6,800 km of roads in about 10 years. Thanks to these big roads, the movement of people as well as sending letters from different regions to the capital city is more convenient, shortening the time compared to before. Along with that, the road system helps to develop trade, the activities of buying and selling goods, agricultural products … take place more efficiently. As a result, the economy has made great development. After the death of Qin Shihuang, the road system was used in many centuries to significantly change the lives of the Chinese people in feudal times.
