Since ancient times, what historical sites have been called "tyranny" and "waste of manpower and material resources", but they have influenced future generations?

The Beijing-Hangzhou Grand Canal and the Great Wall of Qin Shihuang wasted people and money at that time, wasted manpower and material resources, and even the construction of these things led to the collapse of a dynasty.

First of all, the Great Wall has many influences, first of all, spiritual culture. As one of the landmark buildings in China, the Great Wall was called the Eight Wonders by many foreigners, but it was a very expensive project at that time, because people at that time did not have high scientific and technological capabilities. It can be said that many workers died on the road or on the way to build this building. This move by Qin Shihuang was also called tyranny.

It is precisely because Qin Shihuang built the Great Wall that many dynasties were able to resist the attack of nomadic people, which is a cultural symbol for us in later generations. What we see today is the indomitable character and spirit of Qin Shihuang's generation represented by the Great Wall.

The Beijing-Hangzhou Grand Canal is a huge project, which was written by Yang Di. It is reported that Emperor Yang Di built this project to facilitate his southern tour, which aroused public indignation. Because it is very difficult to build this project, the construction of the Grand Canal is not only a loss of labor in one place, but also a serious loss of all labor along the river, because it was built by hands and shoulders, and all of them were accidentally involved in the Grand Canal, even corpses.

The construction of the Grand Canal also laid the groundwork for the demise of Yang Di. At that time, it was also called tyranny, so many people rose up and overthrew the rule of Emperor Yang Di. But the Grand Canal has a far-reaching impact on the present, especially in water conservancy and humanities, which can be said to benefit many people.
