In the first year of Emperor Xiaowen of Qin Dynasty (250 BC), he officially succeeded to the throne, and Zi Chu was made a prince. Three days later, he died mysteriously, and Emperor Xiaowen of posthumous title was buried in Shouling, the shortest reigning monarch in the history of Qin.
Extended data:
Qin Xiaowen's name is Zhu Bo, the second son of Zhao Xiang, the king of Qin. In the era of eldest son inheritance, it is extremely difficult for Zhu Bo to miss the Prince, because there are brothers who mourn the Prince before him. It's not a real name, just like a posthumous title, because he mourns the premature death of the Prince.
Facing the death of the Prince, Zhao Haoqi of Qin was not worried at all. Because he had other sons and was in excellent health, he was awarded the title of Prince in 265 BC and was made a monarch.
When he became the champion of Ann Guo Jun, he was very happy, because he thought that the position of the monarch of Daqin was only one step away from himself, and he was confident that this step was easy. After all, Zhao Haoqi is 60 years old at this time.
Under the background that the life expectancy in ancient times was generally not too long, the king of Qin was 60 years old. Ann's idea was not wrong, but what happened next made Ann very upset, because the king of Qin was in good health and was not sick at all. Ann was 14.
