First, judging from the thoughts of senior officials in the Qin Dynasty, the remains of the first emperor will not be corrupt and stink. From the Spring and Autumn Period and the Warring States Period to the Qin and Han Dynasties, the trend of reburial has been prevalent, which is manifested as "death is like life, death is like existence, and benevolence and wisdom are also prepared" (The Doctrine of the Mean) and "people's morality is generous and cautious" (The Analects of Confucius). In other words, death is as important as life, and careful handling and handling of funeral is the embodiment of filial piety. On this issue, Xunzi, the teacher of Li Si, understands best: "The mourners dress up the dead with the living. Elephants live to send them to die. Therefore, if you die, if you live, if you die, you will start. " He added: "The owners are willing to treat life and death. Life is the beginning of man; When you die, you die. All the good things are done in the end, and human nature is finished. Therefore, a gentleman respects the beginning and is cautious in the end. ..... thick life and thin death. Is to respect his knowledge and slow down his ignorance. It is a treacherous way, and the heart of double rebellion is also. " (Xun Zi Li Lun) In other words, the truth of "Li" lies in paying attention to health preservation and death. Since life and death are equally important, the practice of "rebirth and light death" is a disobedience to the dead parents and kings. True loyalty and filial piety, no matter how loyal and filial, will not be considered as a good beginning and a good end, let alone loyalty and filial piety. These concepts of burying the body with a thick burial will inevitably affect Qin people, especially Li Si, who is deeply influenced by Xunzi's thought and will inevitably pursue Xunzi's thought of "the coffin must be heavy". Xunzi once tirelessly repeated the ancient ritual system: "The emperor's coffin weighs seven times, the vassal weighs five times, the doctor weighs three times and the scholar is heavier." The meaning of "multiple" lies in the protection of the remains. Will the student Reese turn a deaf ear to the teacher's emphasis? Under this idea of reburial, will the body of Qin Shihuang rot and stink? Secondly, judging from the wishes of the first emperor, it is not allowed to let the first emperor's own body rot and stink. Qin Shihuang "speaks ill of death", and ministers "dare not say death" in front of him. When he was seriously ill, he wrote a letter to his son Fu Su: "I will be buried in Xianyang." These seven words show that Qin Shihuang attached great importance to his funeral, that is, "death is like life", which obviously means protecting the remains. This is the only will left by Qin Shihuang before his death, asking Fu Su to go back to Xianyang to handle the funeral. The "burial" in the will is obviously a "thick burial" rather than a "thin burial". This "reburial" is to protect the remains, and people around Zhao Gao, Reese and others certainly understand. There is also a "No.1 Project" implemented day and night year after year-the tomb of Mount Li, which can actually be regarded as the unwritten "will" of the first emperor, that is, buried in Mount Li after his death. This tomb has been built for 38 years, and the construction time is so long. The important reason is that it is "impregnable" and its ultimate goal is to protect the remains of the first emperor. Judging from the historical facts of building a tomb, the anti-corrosion technology of the corpse has been preset and fully prepared. When the first emperor was seriously ill and died, the mentality of senior officials was fearful. Sima Qian talked about their anxiety in Historical Records. At that time, "I was afraid that my sons and the world would change, so I kept it a secret and didn't send out mourning." Protecting the remains should be a powerful measure to prevent "accidents". Is to transport the body to Xianyang intact, so as not to be caught by the sons or the world. So although they are worried, they are not at a loss. They understand that there is nothing wrong with this moment, one is not to send out mourning, and the other is to keep the body intact. Therefore, measures are constantly taken to strengthen prevention, so that the remains of the first emperor can be preserved permanently. Third, judging from the burial system at that time, it can completely prevent the remains of the first emperor from rotting and stinking. Ancient aristocrats emphasized the making of coffins, requiring the use of camphor wood, pine, cypress, paulownia and other materials with aromatic insect-proof function. The ancients thought that "golden jade gives birth to cold", and burying with golden jade can make the body not bad. In the Biography of Yang Wangsun, there is a saying that "jade is in the mouth, but it can't be melted, and depression is withered wax", so there is a saying of "jade clothes" and "jade coffins". The lacquer coffin of Liu Wu's tomb in Shizishan, Xuzhou, is a jade coffin with diamond and triangular patterns, which is the remains of jade coffins seen at present. In the Western Han Dynasty, it was popular for nobles to bury with jade clothes. The emperor used "golden jade clothes", and the princes and ministers used "silver jade clothes" and "bronze jade clothes" in turn. From the Spring and Autumn Period and the Warring States Period to the Qin and Han Dynasties, the funeral system attached great importance to deep burial, which could basically or even completely avoid the adverse physical, chemical and biological factors in the atmospheric space from affecting coffins, martyrs and corpses. Moreover, the coffins are filled with charcoal and herbs directly related to the protection of coffins, funerary objects and corpses. "Lu's Spring and Autumn Annals" also recorded this fact: "The family is rich, the burial is thick, ... the room where the problems are put together, the coffin has been attacked several times. Pile up stones and carbon to surround it. " This is the case in the literature, and so is the revelation of ancient and modern excavations. It can be seen that these external fillers have played an obvious role in preserving the coffin and maintaining the constant temperature and humidity in the coffin. To sum up, even in the tense situation of being busy usurping the throne, people around Qin Shihuang will not give up the protection of the remains of the first emperor, let alone let the remains of Qin Shihuang rot and stink.
