Aisingiorro Dourgen is the 14th son of Nurhachi, a pioneer of the late Jin Dynasty (predecessor of the Qing Dynasty). Born in Hetuala on October 25th in the 40th year of Wanli in Ming Dynasty (A.D. 16 12), his mother Abahai was named Ulan Allah. At this time, Nurhachi was no longer a low-ranking tribal leader, but a "smart and respectful Khan" who unified the various departments of Nuzhen, and was further developing the cause of reunification, laying the foundation for the establishment of the Qing Dynasty. Less than 100 days after Dourgen was born, Nurhachi led an army to attack Wula, and finally destroyed his wife Abahai's home country. Dourgen and his mother are in danger of being left in the cold. However, due to Nurhachi's policy of giving preferential treatment to surrenders and Abahai's resourcefulness and kindness, their mother and son survived the difficulties safely. Over time, Dourgen also entered the ranks of Tai Chi. Nurhachi has fifteen sons. When he died, he appointed his favorite and most valued fourteenth son, Dourgen, as his successor. But Dourgen was only fifteen, too young. With the yellow flag and yellow flag in the Eight Banners of the Later Jin Dynasty mastered by himself, Huang Taiji was powerful and gained the right of inheritance. ?

In A.D. 16 16, after the establishment of Nurhachi, the State of Jin was named Destiny. Two years later, he denounced the "seven great hates" and launched an attack on the Ming Dynasty, which opened the prelude to the Ming and Qing wars. In the successive victories of the anti-Ming war, the internal contradictions and struggles in the late Jin Dynasty also occurred constantly. In September, the fifth year of the mandate of heaven (1620), Nurhachi announced the deposing of Crown Prince Belle Daishan, and "established A Min Taiji, Mangu Taiji, Huang Taiji, Dege, Yuefu, Jilalang, Ajige Aqian, Duoduo and Dourgen as Heshuo Zhens". In other words, from this time on, Dourgen became an eight-year-old child in the Heshuo team participating in state affairs.

Such an important action to change the post-Jin political structure began in March of that year when Nurhachi abandoned the rolling queen Fu Cha. At that time, Fu Chashi's doctor Jin added four counts to his head, but all of them lacked sufficient evidence. For example, one of the four major crimes is that Daishan and Fu Chashi have an ambiguous relationship. In fact, someone set them up. After Fu Cha was abandoned, Dourgen's mother Abahai succeeded her as Dafu Jin. In this way, Nurhachi loves me, loves my dog, and Dourgen and his brothers Azig and Dodo have risen in status.

In addition, Daishan lost his father's favor because he cared about everything, and abused his son because he listened to the slanderous remarks of his second wife, which brought an excuse against him to those who coveted his position, resulting in his "prince" Dourgen's position being deposed as mentioned above. In this way, under the system of Nurhachi's common governance, the Dourgen brothers became one of the pillars of the balance of power for the first time. Dourgen is no longer the flag owner Baylor at this time, but just with his younger brother Duo Duo. After all, he is still a minor child, and his political status is not as good as Aziz's, or even more. During the period of destiny, there was no trace of dourgen. In the first year of the mandate of heaven (16 16), you can personally worship the royal family of Nurhachi, among which Azig and Dodo rank sixth and seventh, and Dourgen is not allowed to participate. Nevertheless, in addition to Sibeile and his brother, Dourgen is the most outstanding master, surpassing Dege, Girallang, Abatai and others. It was also a powerful tai chi at that time.

However, the good times did not last long. Nurhachi died in the eleventh year of Destiny (1626) on August 11th. On his deathbed, he summoned his beloved wife, Ula Abahai, who seemed doomed to die. However, Baylor was worried about the rapid growth of the strength of Dourgen's three brothers, so nine hours after he was hailed as Khan in Abahai, he forced him to commit suicide, claiming that this was Mao's "legacy". At this time, the Dourgen brothers are in the most difficult situation. They have not only lost their political dependence, but also faced the struggle of their brothers for their flags. Who knows what will happen in the future?

After Huang taiji succeeded to the throne, although he did not operate on them, he also degraded their status through the pledge of three loyalties. In particular, Huang Taiji suppressed their two white flag forces in a series of actions to strengthen imperial power. Even Daishan, A Min and Man Gourtay Baylor were squeezed everywhere. How could the Dourgen brothers be spared? However, Huang taiji knew that if he wanted to weaken the influence of Sanbaylor, the greatest threat to the imperial power, his own strength was not enough, and he had to win over and support some brothers, sons and nephews who had little conflict with him, including Dourgen.
