Why is real gold called Emperor Yuzong?

Zhenjin, the eldest son of Kublai Khan in Yuan Shizu, was the wife of Queen Chabi Hongjila. After Kublai Khan ascended the throne, Zhenjin was made the Prince of Yan. From Yuan Dynasty to Yuan Dynasty, Yuan Shizu adopted Chen Han's suggestion, changed the old Mongolian system and established the throne. Thus, the eldest son Jin Jin was officially canonized as the Crown Prince. In the 22nd year of Zhiyuan, a minister wrote to Yuan Shizu asking for the real gold of the Crown Prince and the Zen position of Yuan Shizu, which caused Yuan Shizu's displeasure. Hearing the news, Jin Jin was frightened and finally depressed, so he died at the end of the year.

After King's death, Yuan Shizu made him Prince of Xiao Ming. In the 30th year of Zhiyuan, timur, the great-grandson of Huang and the third son of Zhenjin, was officially established. The following year, Yuan Shizu died, and Timur, the grandson of the emperor, officially acceded to the throne as Yuan Chengzong. After he acceded to the throne, Yuan Chengzong honored his father Zhenjin as emperor, went to the temple with the name of Yuzong, and died for Wen Huidi Xiao Ming. From then on, Jin, who had not been an emperor for a day, officially became Yuan Yuzong.

Speaking of which, I think everyone will think of Ming Taizu's eldest son Zhu Biao. Indeed, Zhu Biao and Zhen Jin are very similar. Both of them were trained as successors by the "founding emperor", but they both died in front of their fathers. Then, it was their son who became the great-grandson of the emperor and eventually succeeded to the throne. After their son became emperor, they were also honored as emperors by their sons before they became emperors for one day. After Zhu Biao ascended the throne in Zhu Yunwen, Ming Huidi, he was honored as a well-off emperor.

However, Jin Jin is lucky to compare with Zhu Biao. After the war in Jingnan, Ming Huidi had nowhere to go. The royal family moved from the office of the eldest son to the concubine of the fourth family, that is, the Judy family of the Ming emperor. Now that the son is not the emperor, Zhu Biao's position is embarrassing. Therefore, Ming Chengzu reduced his eldest brother Zhu Biao from Emperor Xingzong Xiaokang to Prince Wen Yi, who was hunted by his father Ming Taizu. It was not until the first year of Hong Guang in Nanming that Zhu Biao became a well-off emperor again.

Zhen Jin is much luckier than Zhu Biao. Although his son Yuan Chengzong was the last heir, Wu Ying Zong Haishan and Yuan Renzong Ai Yu Ba Li Bada, who succeeded him later, were his own grandchildren (the second son of Zhenjin and the son of Baiyuan Shunzong Ansa Mabala). Although the brotherly relationship between Yuan Wuzong and Yuan Renzong triggered a bloody struggle for the succession of the throne in the Yuan Dynasty, and a large number of people were constantly changing, the throne was always in the golden vein. So, Jin Jin was lucky not to be demoted like Zhu Biao, but to be his emperor Yuzong in the underworld.
