In July of the 37th year of the first emperor of Qin Dynasty, the first emperor who traveled all over the world shot a big fish by boat in Zhifu. After that, he sailed westward along the coast and set foot on the return journey to Xianyang. When they arrived at pingyuanjin, the first emperor suddenly fell ill. As a result of divination, there are mountain ghosts in the north. The first emperor sent his confidant Minister Meng Yi to Dai County to sacrifice to the famous mountain god instead of himself, praying for the elimination of disasters and diseases.
When the car crossed the Yellow River and arrived at the dune platform, Shi emperor's condition deteriorated rapidly and had to stop. The first emperor foreboding ominous, emergency in bed before oral edict, arrangements. In this way, the first emperor of Qin issued the imperial edict. This is the famous imperial edict in history, and it is also a controversial historical case. At that time, there was a saying in the imperial edict issued by the first emperor of Qin Dynasty: when he arrived at the plain, he fell ill. The first emperor spoke ill of death, but his ministers dare not. When he got sick, he gave his son Fu Su a seal saying, "I will be buried in Xianyang." It means to let the salary help Su run the future generations.
However, when the first emperor dictated the imperial edict, Hu Hai, his youngest son, was the only son around him, and also his beloved son who intended to be his successor. However, at the last moment of decision, he did not tell Hu Hai, who was close to him, but Fusu, who was far away in Shangjun. We can only explain this matter as follows: after ten months of personal investigation, the first emperor finally thought that Hu Hai was not suitable to be his successor. He swayed from Fusu to Hu Hai, and then from Hu hai to Fusu.
When the first emperor dictated the edict, there were three important figures present, Hu Hai, Li Si and Zhao Gao. As we have already mentioned, Hu Hai was a young man who had no political ability or ambition. He accepted his father's decision without any extra reverie.
However, Zhao Gao, Hu Hai's teacher, has another idea. At that time, Zhao Gao's official position was the order of Zhongche government and the official seal. After the imperial edict of the first emperor was recorded, he had to seal it and send it out. He detained the imperial edict, instigated Hu Hai and Prime Minister Lisi, destroyed the original imperial edict, and forged a new imperial edict, ordering his eldest son Fusu to commit suicide and making his youngest son Hu Hai his successor. This matter is known as "the plot of sand dunes" in history.
This issue about the imperial edict of the first emperor has been raised and questioned for thousands of years. In fact, it is not limited to the imperial edict of the first emperor. In the whole history of China, the imperial edict is a complex problem that constantly appears and is always unclear.
