Emperor Taiding of the Yuan Dynasty was a weak and indecisive emperor, during his reign, Zuo Cheng xiang fell to The Sha to control the government, most of the court was his cronies, at the same time, the empress did not manage the harem well and frequently interfered in politics, and her behavior was extremely arrogant. Emperor Taiding felt that he had no place to play in the court, and he was also suppressed by his wife, and his heart was very depressed, and he could only rely on the study of Buddhism to pass the time and dispel the depression in his heart. But in the end, it was depressed.

After the death of Emperor Taiding, his son Asoki VIII should have ascended the throne, but in order to further consolidate his position in the imperial court, Zuo Chengxiang had been dragging his feet to prevent Asokji VIII from taking the throne. After a long time, everyone thought that it was a plot to usurp the throne, and after the rumors spread, they were heard by some people with hearts and began to use this matter to make a fuss.
In August of the same year, Emperor Taiding's cousin Timur staged a coup d'état in which he threatened officials in Dadu to follow him and become emperor. However, because he could not return to Dadu in time at this time, and the distance was very far, even if he rushed back to Dadu as soon as he received the news, it would take a year to return to Dadu, so Yan Timur thought of a good note, because Heshi's younger brother Tu Timur was very close to Dadu, so Yan Timur recalled Tu Ti Mu'er to Dadu and asked him to "sit" on the throne for his brother first. In September of that year, Tu Timur ascended the throne as emperor and declared to the outside world that as long as he returned to the capital, he would immediately cede the throne to him. As long as there is a little discernment ability, you can see that these two people are lying, if you really want to watch for his brother's throne, then it is good to supervise the country, why should you be an emperor? Wouldn't it be superfluous to wait until the peace returns and then abdicate? Therefore, Tu Timu'er had no intention of returning the throne to Heshi.
But what we must not forget is that there was also a prince in Shangdu who had not ascended the throne, Asokji Viii, and when Helasha heard that Tu Timu'er had been proclaimed emperor in Dadu, he panicked at that time, and quickly supported Asoki Viii as emperor and sent troops to attack Dadu. At this point, the "Battle of the Two Capitals" in the history of the Yuan Dynasty broke out. In the end, the war ended with the surrender of Raisa and the disappearance of Asokyo.
At this time, Heshi was also about to return, and in order to show that he really only "saw" the throne for his brother, Tu Timu'er sent someone to welcome Heshi back to the dynasty. In fact, Tu Timu'er thought that the Peace Society, because he did not have any role in this war, was so far away from the capital that he refused to accept the throne because he fled in defeat. But Heshi didn't think so, he felt that because he was the eldest son, Tu Timu'er did all this as he should. So on the way back to the dynasty, he installed his own manpower, and Tu Timu'er was greatly dissatisfied. He began to find ways to prevent Heshi from entering the capital, and soon after Heshi arrived at Wang Kuchadu, chaos ensued.
On the first day of August, Heshi arrived at King Kuchadu, and the next day Tu Timu'er went to see him. However, four days after the two brothers had met, Heshi died. He shi had only been emperor for eight months, and what was even more ridiculous was that he did not even enter the capital and died before the dragon chair was seen. Tu Timu'er naturally continued to be emperor, and this result also made everyone very satisfied, which was a great joy for everyone.
