1. Young war wounded
Emperor Taizong and the military leader Duan Zhixuan leapt on horseback and went deep into the thieves' formation. The enemy's arrows rained like rain, and Emperor Taizong was hit by the arrows, and he pulled back to fight and clashed with his position. After being furious, he killed dozens of people with his hands, and the two blades were exhausted, and the blood flowed into the sleeves, spilling and resuming the battle. —— "Zizhi Tongjian"
According to the Zizhi Tongjian record, Tang Taizong once went deep into the enemy camp in his early years of battle and was shot by random arrows. Tang Taizong, who was young and powerful, pulled out his arrow and continued to charge and kill, and continued to kill dozens of people. When Emperor Taizong of Tang was young, Li Shimin was also a very brave and warlike general, and he followed his father in the southern conquest of the northern war and established immortal merits for the Tang Dynasty. However, if he could not be injured on the battlefield, Tang Taizong would inevitably be seriously injured if he rushed out in the shadow of the sword and light sword. According to this record, we can infer that Tang Taizong once suffered a serious arrow wound. Judging from this, the death of Emperor Taizong is likely to be caused by the long-term unhealed wounds on the battlefield.
2. Wartime life is irregular
The people of the world tasted the handsome light riding to the enemy, and the horses were scattered, and the people of the world slept alone with a knight on the hill. ...... In a few moments, Jingde and Xiangxiang sneaked in to guide the elite to ride to help Wang Xingben in Pusaka, and the people of the world rode three thousand on foot, from the middle road to Anyi at night, invited to attack, and broke it, and Respected Virtue and Xiang only spared themselves, captured their people, and returned to Baibi. —— "Zizhi Tongjian"
Judging from this passage of Zizhi Tongjian, when Tang Taizong was fighting on the battlefield in his early years, he often ran all night to seek war, and he fought very hard. Then we know that long-term irregular work and rest will lead to an unhealthy state of the body, so that long-term conquests accumulate, even if the body is very strong before, it may also fall into the root of the disease. Then we may as well speculate that Tang Taizong's death may also be caused by long-term irregular schedules and all-night raids and battles.
In March of the twentieth year, Gengwu decreed: "Since the year of the Dawn of The Year of The Dawn of The Year, when the Road is lost, the huaisheng and so on, all the wilderness is painted." It is to use the heartache, to save the fire, to take the battle as the bean, and to take the gango as the chapter. Sunset is not far away, Ningji is in all directions; hunger is not enough to eat" - "The YuanGui of the Book"
Regarding the statement that Tang Taizong fell ill due to his late-night raids and battles in his early years, which led to irregular work and rest, we can confirm it according to Tang Taizong's self-description in his later years. Tang Taizong said that he had been unable to sleep at night and was hungry because of the war, causing symptoms such as headaches.
Then, some people will ask, Qin Qiong, Wei Chi Jingde, Cheng Yaojin, and others who fought with Tang Taizong in the early years were also unable to sleep at night, and their work and rest were very irregular, so why could they live a long life? Therefore, the death of Tang Taizong may also be related to other factors.
3. Overwork
Tang Taizong was a famous Ming Emperor in Chinese history, and in order to eliminate the insult of killing his brothers in the Xuanwumen Rebellion, he slept at night like walking on thin ice, creating the foundation of the rule of Zhenguan for the Tang Dynasty.
"There are many articles than there are books, and the walls of the house are always sticky, and they are in and out of the province. Therefore, those who are tireless want to do their best to be subordinate. Every thought of politics, or three more square sleeps. I also hope that the gong will be tireless in their hearts and be resilient to the vice-mindedness. ——" Zhenguan Politicians
"Every night he thinks about the affairs of the people, or does not sleep until the middle of the night." But I am afraid that the governor and the assassin Can raise the people will not be able to do so. Therefore, his name is recorded on the screen, sitting and looking at it continuously, and if there is any good deed in the official, it is also listed under the name. Living in the deep palace, the audio-visual cannot reach far, and the only people who are entrusted are the governor and the assassin, and this generation is related to the control of chaos, especially the people. ——" Zhenguan Politicians
According to this record in the "Zhenguan Politicians", the tang dynasty had a lot of administrative affairs, and Tang Taizong was also very industrious. He often excerpted important places for his courtiers and pasted them on notes in the study. In order to be able to deal with the affairs of the people in a timely manner, he often could not sleep at night, and the names of officials would be written down on the screen to facilitate the assignment of tasks. During the reign of Emperor Taizong of Tang, he could not sleep at night for a long time, and his high concentration of spirit may also make him exhausted, leading to premature death in his early years.
4. Take dan medicine
In order to prolong life, or to improve energy, ancient emperors often took some elixirs refined by warlocks. In the early years of Tang Taizong, he once satirized Emperor Wu of Han, who was obsessed with the art of immortality. He once told his courtiers that the so-called immortality is a lie. However, perhaps because people are afraid of death as soon as they are old, Tang Taizong was also fascinated by huang laozhi in his later years, and he often took the elixir refined by warlocks to prolong his life. In addition to some ordinary herbs, dan medicine generally contains highly toxic minerals. For example, warlocks often use cinnabar, which is a highly toxic mineral. Therefore, Tang Taizong's obsessive elixir was very likely to cause him to die of chronic poisoning.
5. Mental illness
Emperor Taizong of Tang killed his brother during the Xuanwumen Rebellion due to his early involvement in the conquest of concubines, and then forced the palace to force his father to make himself crown prince. The unusualness of this family relationship is likely to lead to Tang Taizong's psychological illness. There is a story about the god of the door in ancient China, and it is said that Tang Taizong often dreamed that his brother Li Jiancheng and younger brother Li Yuanji, who had been killed by him, came to ask for their lives, so they tossed and turned, and could not sleep at night. Qin Qiong and Wei Chi Jingde could only be sent to stand guard outside his bedroom door, and since then Qin Qiong and Wei Chi Jingde have been rumored to be door gods. With this in mind, we can know that Tang Taizong's early years of snatching and killing his brother caused him psychological illness. Then, psychological diseases should also be a cause of premature death.
In the later years of Emperor Taizong of Tang, crown prince Li Chengqian attempted to murder his brother. After this matter was discovered by Tang Taizong, the crown prince tried to plot again. The actions of the crown prince Li Chengqian were almost the same as Tang Taizong's actions in the early years of killing his brother and forcing his father. Emperor Taizong of Tang was furious and immediately deposed the crown prince Li Chengqian. Soon, the crown prince Li Chengqian died of depression. His favorite son was forced to die by himself, how could Emperor Taizong not feel bad. Since then, Tang Taizong's spiritual head has plummeted, and six years later, The Heavenly Khan Tang Taizong Li Shimin died.
From here, we can deduce that the deposed and death of the crown prince Li Chengqian was the fuse that caused Tang Taizong's early death. Due to the prince incident, Tang Taizong was depressed and depressed for a long time, coupled with the war wounds and fatigue in the early years, as well as the overdose of Dan Medicine and other inducements, which led to the fall of Tang Taizong Li Shimin, who was once young and strong.
conclusion:
To sum up, I think that the reason why Tang Taizong, who was once rich and powerful, went only 51 years old was because of the psychological illness caused by the Prince Incident as the fuse, coupled with the old wounds on the battlefield in the early years and the worries after the government, as well as the excessive consumption of poisonous Dan medicine as an inducement, which together led to the fall of a generation of "Heavenly Khans".
