In order to save China, what building did Qin Shihuang build under the column of shame?

Qin Shihuang built the Great Wall of Wan Li, which has been passed down through the ages. It is because of the existence of the Great Wall in Wan Li that the Han Dynasty after the Qin Dynasty was able to resist the attack of the Hu people. Qin Shihuang built the Great Wall himself to prevent the Qin Dynasty from being destroyed by the Hu people. Although the conference semifinals didn't attack Qin on a large scale, the later Han Dynasty did resist the conference semifinals' attack with the Great Wall of Wan Li.

In 22 1 year BC, Qin Shihuang unified the six countries. At that time, after Qin Shihuang consolidated his rule, he asked some people who were good at predicting why the Qin Dynasty would perish. Those forecasters replied: "People who died in the Qin Dynasty, Hu Ye!" It was after listening to these people's predictions that Qin Shihuang seriously began to consider how to resist the invasion of the Hu people.

Since Shang Dynasty, the Hu people have been a great threat to the Central Plains regime. Because the Hu people are nomadic people, they can freely invade the Central Plains. Some small countries may be destroyed if they are not careful when they are attacked by the Hu people. So Qin Shihuang never underestimated the threat posed by the conference semifinals.

Qin Shihuang thought for a long time and chose to build the Great Wall of Wan Li to resist the invasion of the Hu people. At that time, Qin Shihuang gathered countless civilian workers to the north to build the Great Wall of Wan Li, but behind the Great Wall, he paid too much blood. Countless migrant workers died on the steps of building the Great Wall because of illness and fatigue. At that time, the slogan of resisting the tyrant's rule spread everywhere in the land of the Qin Dynasty. When the people's dissatisfaction accumulated to a certain extent, the peasant uprising broke out in the Qin Dynasty.

Liu Bang suffered a fierce attack from the Hu people in the early Han Dynasty. At that time, the conference semifinals were very powerful, and Liu Bang was badly hurt because he had just experienced a big war with Xiang Yu. In the end, Liu Bang relied on the Great Wall of Wan Li built by Qin Shihuang to deter the Hu people. It can be said that the situation envisioned by Qin Shihuang was not really encountered until Liu Bang established the Han Dynasty. Although Qin Shihuang built the Great Wall of Wan Li under the stigma, the Great Wall of Wan Li he built did avoid the end of national subjugation for Liu Bang.
