Why is the death of the ancient emperor called "death"

Birth, aging, illness and death are the natural laws of life. The ancients had many taboos about death, so "death" had many different nicknames. The death of the emperor is called death, collapse, death, and the people are called death, death, death and so on. "Selected Works of Zhuge Liang" and other ancient books record: "Before the first emperor started his business, the middle road collapsed." And "Fourteen Chapters of the Tang Dynasty": "Emperor Wen died without a will." In addition, Bai Juyi's "Xin Yue Fu Wei Xingliang" in the Tang Dynasty: "The color of Hongxuan is not dry. Last year, the body moved to the owner today. " Then, why was the death of the ancient emperor called "death"? Driving, originally a general term for ancient means of transportation, or specifically refers to the emperor's car, such as car driving and Luan driving. Uploaded in the Book of the Later Han Dynasty: "When the emperor came out, there were big drivers, French drivers and small drivers." The carriage driving of ancient emperors can be divided into three types: four-wheeled carriage, French coachman and small coachman. When the emperor travels, the biggest guard of honor is the carriage, which is above the French coachman and the coachman. In addition, it was also uploaded in Zhengzitong written by Zhang Zilie in the Ming Dynasty: "In the Tang Dynasty, the son of heaven rode as an official." Therefore, gradually "driving" has become an ancient title for the emperor, or used to refer to the emperor and the son of heaven. Such as escort, driving, waiting. According to Shuo Wen Jie Zi, "A landslide is bad, and friends ring from the mountain." So the original meaning of collapse is the collapse of mountains. For example, "Zuo Zhuan Cheng Gong Five Years" uploaded: "Liangshan landslide." In ancient times, people often regarded the death of the son of heaven very seriously, and often used landslides as metaphors, so the death of the emperor was called "collapse" from the Zhou Dynasty. For example, it is recorded in the Book of Rites: "When the emperor died, he said' collapse', the vassal said' death', the doctor said' death', the scholar said' decline' and Shu Ren said' death'." Collapse, death, death, failure and death are all ancient names of death, but they are all class-oriented. In ancient times, death can be used to refer to or address the emperor, while collapse means that the emperor died like a mountain collapsed, so "death" is a name used by the ancients to refer to the death of the emperor, and only the death of ordinary people can be directly called "death".
