Suspected cement concrete was found in Yangshao village site more than 5000 years ago. Is ancient infrastructure crazy?

Cement concrete suspected to be 5,000 years ago appeared in the site excavated in Yangshao Village, which aroused the infinite reverie of netizens and made it crazy to guess the ancient infrastructure in China. Maybe it's true. Infrastructure and agriculture may be traditional arts in China.

1. National defense infrastructure? The Great Wall of Wan Li, when you think about it, there are quite a few infrastructures in ancient China. The Great Wall of Wan Li is a living example, which is mainly used to resist foreign invasion. That was the national defense infrastructure of that year. It seems that the ancient sages have long realized the importance of infrastructure, and the Great Wall has been continuously relayed in later generations. Until now, the length of a circle around the earth and the national defense infrastructure are yours!

Second, water conservancy infrastructure? Beijing-Hangzhou Grand Canal, Dujiangyan With the development of our country and the imbalance of water resources in the whole country, the problem we have been facing for a long time is that floods often occur in places rich in water resources. Where water resources are not abundant, it is dry all the year round and yellow sand is all over the sky. Water conservancy project is one of many solutions. From the Three Gorges Dam to the South-to-North Water Diversion Project, it witnessed the story of the working people in China fighting wits with nature, and Dujiangyan water conservancy project, an ancient infrastructure, directly established the status of Sichuan as a land of abundance. Although the Beijing-Hangzhou Grand Canal was controversial, it had great economic benefits for water conservancy and transportation at that time.

Third, transportation infrastructure? I have to say that the Qin Dynasty made great contributions to the traditional art of our infrastructure. In addition to the construction of the Great Wall of Wan Li, a national defense infrastructure, unified surveying is undoubtedly of great reference value to future generations. The cars here are all on the same track. Think about it carefully, isn't it also the infrastructure construction of ancient transportation? Unified construction of standardized roads, convenient for marching or caravan travel. These are the rich wisdom achievements of our ancestors. It seems that if you want to be rich, you should build roads first. The ancients still understood this truth. In the wisdom left by the ancients, we can still see the momentum that we have become a madman in infrastructure, and we will continue to carry forward these precious traditional arts.
