Nurhachi has faced the problem of establishing a reserve many times in history, but each time it has ended in failure. He was the first to choose his younger brother Shulhaqi, but due to differences of opinion and the provocation of the Ming Dynasty, he eventually parted ways, and Shulhaqi was executed. Secondly, he chose his eldest son, Chu Ying, who had made great achievements in the battle and was regarded as a successor by Nurhachi, but because of his arrogance towards other sons and nephews and important subordinates, and even plotted to usurp the throne, he was finally deposed and executed. For the third time, Nurhachi chose Daishan as his prince, because Daishan was the son-in-law born to his wife, with outstanding military achievements and high prestige, known as "Guying Baturu", the first of the "Four Great Beylers", with a gentle personality and generosity, Nurhachi left a legacy to entrust his family to Daishan. However, the "Deinze Denunciation" in 1620 and other factors eventually shattered Daizen's dream of becoming a prince. Nurhachi's bumpy experience on the issue of establishing a reserve has become an eternal topic in ancient history. Nurhachi's fourth queen, Ulanala Abahai, was the mother of Azig, Dolgon, and Dordor who was the target of the crowd.
Deinze exposed to Nurhachi the three major misdeeds of the eldest concubine Abahai: first, she privately sent food to Daishan and Huang Taiji, who "received but did not eat", while Daishan "received and ate", and behaved very happily; Secondly, Abahai carried Nurhachi and others to Daishan's house many times, and dressed up at parties many times, and had an affair with Daishan; Third, she went out of the palace late at night many times, and her whereabouts are unknown. When Nurhachi learned about it, he launched an investigation and confirmed that it was true, and Abahai and Daishan also confessed. As time passed, the situation expanded, gradually drifting away from the truth. Nurhachi expelled Abahai from the palace for a year under the pretext of stealing the treasures in the palace, causing Daishan to become dissatisfied and distrustful of Nurhachi. The second is the "Dai Shan Abuse Incident". Because Daishan favored his stepwife, he abused his ex-wife's sons Shuo Zhi and Yue Tuo for a long time. Rumors spread that Shuo was being abused in a situation similar to that of Jaisangubele, and that he was preparing to defect to the Ming Dynasty. Daishan and Amin advised Nurhachi to kill the two. After Nurhachi's careful investigation, he found that the responsibility was entirely on Daishan and Amin, so he released Shuo Shan and Zhai Sangu and reprimanded Daishan and Amin. Seeing that Shuo was not executed, Dai Shan continued to abuse him at the instigation of his stepwife, and again asked Nurhachi to be executed.
Nurhachi was extremely angry, believing that Daishan's behavior was not worthy of being the Great Khan of Houjin, and deposed Daishan's succession qualifications, and ordered him to split his family, and the eldest son Yue Tuo led the two red flags under his command. Nurhachi was dissatisfied with Daishan's ability to handle family affairs, and there was still residual anger at the "Deinze Whistleblowing Incident", but in any case, Daishan paid a terrible price for this and lost his position as prince. After Nurhachi's death, Daishan father and son supported Huang Taiji and made him succeed to the throne smoothly. Nurhachi died in the sixth year of the Apocalypse (1626), without specifying a successor, leaving only the system of "Eight Harmony and Shuobeile Co-governance". In this context, Aixin Jueluo Huang Taiji has become a strong contender for the new Khan. Yue Tuo and Sakhalian, the two sons of Dai Shan, found Dai Shan on the same day and unified their opinions in support of Huang Taiji: "The four Belle talents are crowned with virtue, and they are deeply in line with the sacred heart of the first emperor, and everyone is satisfied, and they should succeed to the throne as soon as possible." No one agrees, who disagrees. At the court meeting the next day, Daishan father and son took the lead in supporting Huang Taiji.
Because Dai Shan is the first of the "Four Great Baylors", and his family is in charge of the two red flags, plus the Zhengbai Flag in charge of Huang Taiji, he has an advantage in strength, and there is no room for opposition from other Baylors, so Huang Taiji successfully ascended to the throne of Khan. Dai Shan chose to support Huang Taiji instead of fighting for his own rights, on the one hand, because he was deposed before, and it was not appropriate to fight again, which would also lead to the dissatisfaction of other Baylors, which could lead to chaos. On the other hand, it is also because Dai Shan's character is not suitable for this kind of decisive behavior. Later, when Huang Taiji changed his title to emperor in the ninth year of Chongzhen (1636), he named Dai Shan as Prince Heshuoli, which reflected Dai Shan's performance and role during Huang Taiji's ascension to the throne. Although Dai Shan has moved away from the inner circle of power, he still enjoys high prestige and status in the court. After the death of Huang Taiji, Duoduo hoped that Daishan would succeed him, but at this time, Daishan had no intention of fighting. In the eighth year of Chongde in the Qing Dynasty (1643), Huang Taiji died, and once again fell into the struggle for the throne, and Aixin Jueluo Duoduo played an important role in this competition. The Daishan family made great achievements in the rise and unification of the Qing Dynasty. However, the death of the two most popular sons, Yueto and Sakhalian, has clouded the family's future.
The rest of his son, Shuo, was disgusted by him, and his beloved Mandahai was still young, and his other grandson, Adaali, was not liked by him. It can be said that the Daishan family has fallen into the dilemma of "** people are hard to find". Faced with the attack of Hauge, Dolgon, and other banner lords, the Daishan family was unable to resist, and finally he resolutely chose to withdraw from the struggle for the throne. Prince Zheng Jierharang proposed Fulin to succeed him, and was supported by Dolgon, Dai Shan and others, and Fulin successfully ascended the throne and became Emperor Shunzhi. Although Dai Shan did not ascend to the throne, he and his entire family were praised and remembered for their personal and family exploits in the establishment and unification of the Qing Dynasty. Dai Shan was the first member of the eight "Iron Hat Kings" of the Qing Dynasty, and his family occupied three seats among these eight, namely Dai Shan, Yue Tuo, Sakhalian and their descendants. This lineage created the family tradition of the three "Iron Hat Kings" of Prince Heshuoli, King Dorakqin and King Doro Shuncheng, which is unique in the history of the Qing Dynasty.
