Qin Shihuang Mausoleum, Sima Qian's record and description of Qin Shihuang Mausoleum in Historical Records is: "Wear three springs, descend copper, and be buried in the palace." Let the craftsman make a crossbow, and people who wear it at close range need to shoot it. Take mercury as a hundred rivers and seas, instill machines, there is astronomy on the top and geography on the bottom. Take mermaid cream as a candle, and it will last for a long time. "
It is said that the mausoleum of the First Qin Emperor was built when Ying Zheng became king. His mausoleum was built for 39 years until the death of Qin Shihuang. After Qin Ershi Hu Hai succeeded to the throne, it took more than a year to basically complete it. The designer of this mausoleum is Prime Minister Reese, and the supervisor is Zhang Han, a junior official. Zhang Han, the prime minister, or Zhang Han, a junior government official, must have a complete drawing plan to build the Mausoleum of the First Qin Emperor, and Ying Zheng's approval is needed to organize personnel to build it. This is also a very huge project.
The first step in building the imperial tomb is to choose a good address, and then plan according to the geographical location at this time, which naturally involves drawings and planning. Even if there are complete planning drawings and general outlines, they should be shown to Ying Zheng, the king of Qin at that time, and construction can only be started after his approval. These documents about the mausoleum, in addition to Li Si and others who were responsible for the construction, must also have related records in the Shaofu Order responsible for the construction, so the mausoleum of the First Qin Emperor was not a relatively confidential thing at that time, and naturally many people knew it.
Do you have any drawings of the imperial tomb? After Qin Shihuang unified the six countries, he began to expand his own imperial tomb, which inevitably involved drawings and planning. The person in charge of building the imperial tomb must have relevant drawings, as well as the palace where Qin Shihuang is located. After all, when Li Si built the mausoleum for Qin Shihuang, he directly recruited 700,000 to 800,000 people. Without drawings, it is impossible to build by feeling.
As for why the structure of the imperial tomb is easy to be known, the key reason is that the imperial tomb was built in the second year after the unfortunate death of Qin Shihuang. If it was built before the death of Qin Shihuang, it is easy to clean up all the relevant materials of the imperial tomb with Qin Shihuang's ability and prestige. But the mistake is that it was not completed until the second year after his death. At this time, the Qin dynasty was already in a turbulent period. As an emperor, Hu Hai was basically a puppet, and naturally he didn't spend much time and energy on it, so many relevant records were preserved. After the establishment of the Han Dynasty, many things in the Qin Dynasty belonged to the Han Dynasty, and these documents and drawings were no exception.
