Although the Great Wall has lost its significance in today's society and can only become a landmark building for everyone to play, in ancient times, the Great Wall has great achievements, and in the history of Chinese civilization, it plays a vital role. China is the only country in the four ancient civilizations that has not had a cultural fault, the special geographical environment has created the current China, east of the sea, southwest of the mountain barrier, the north of the Great Wall of ten thousand miles of obstruction, so that the northern nomads can not invade the land of our central plains at will, so as to ensure the prosperity of our country for thousands of years.
From the beginning of the Zhou Dynasty, the Great Wall has begun to be built, although the scale at that time is still very small, until the Qin Dynasty Qin Shi Huang ordered large-scale construction. At first, people used mud and grass, the most basic adhesive, although it is much stronger than simple mud, but it is not very strong, in the Zhou Dynasty, people found lime, and then combined lime and clay and sand to form a triad, using triad soil to build the Great Wall is much stronger, and the cost is not high.
At the end of the Warring States period, it was found that adding glutinous rice syrup to the triad soil could make the adhesion of the triad soil to a higher level, so in that era there was a glutinous rice triad. However, because the grain production at that time was very low, people had problems eating, and they were not willing to use glutinous rice to make this glutinous rice triad. After Qin Shi Huang unified the Six Kingdoms, he was not satisfied with the original triad mud and decided to add glutinous rice to it, and for the best degree of solidity, it was also proportioned according to the best proportions.
This decision caused an uproar in the DPRK, and the ministers opposed such an approach, because it was too expensive, lime, sand and clay were very good to make, inexhaustible, but glutinous rice itself was the foundation of governance, originally the construction of the Great Wall was a very huge project, if you add glutinous rice, it is simply an astronomical number. But Qin Shi Huang was a person who pursued the extreme, how could a glutinous rice make him retreat, and in the end, Qin Shi Huang ordered that glutinous rice must be added to build, and finally built the Great Wall.
Qin Shi Huang gave the emperors of later generations a very good head, the emperors behind them in the construction of the Great Wall are to add glutinous rice in the mud, the most representative is the Ming Great Wall, Zhu Yuanzhang strictly in accordance with the instructions that Qin Shi Huang must join the glutinous rice to execute, the Ming Great Wall is also built behind the Qin Great Wall to offend a strong section of the Great Wall, but Qin Shi Huang's one feel is also sitting on the name of his tyrant, but as far as the emperor is concerned, Qin Shi Huang can't consider only the moment, and the merit is what Qin Shi Huang thought.
