Huang taiji died suddenly on the ninth day of August in the eighth year of Chongde (1643). Because there was no heir reserved, after this sudden incident, his fourteenth brother, Prince Dourgen of Heshuo Rui, who was in charge of Zhengbaiqi, launched a fierce battle for the throne with his eldest son, Prince Haug of Su. The contenders were evenly matched and deadlocked. The clever Dourgen made a motion on the spur of the moment, taking Fu Lin, the ninth son of Huang Taiji, as the emperor, together with Heshuo Zheng Qinwang Jierhalang and his assistant government, and the result was passed. On August 26th, Fu Lin ascended the antlers throne of the Dugong Hall in Shengjing, which is the mercy seat. The following year, Yuan Shunzhi was changed.

. In the eighth year of Chongde (1643), Huang Taiji "suddenly died" in Shenyang Qingning Palace. Because of his sudden death, he did not make any arrangements for the things behind him, so the princes and ministers quickly brewed a fierce battle for the throne behind their grief.

At that time, Daishan's two red flag forces had been weakened, and he himself was over 60 years old, and he no longer asked about the failure of state affairs. Among their sons, the most talented Yuefu and Sahalian died when they were young, and the rest of Fu Shuo was not liked by Daishan, so they went into the sea and had no right to speak. The third generation Addali and the flag owner Luo Luohun were unwilling to lag behind, but they were repeatedly suppressed by Huang Taiji during the Chongde period. From this point of view, the two red flags, old and small, have lost their competitive advantage. But with Daishan's qualifications and the strength of two red flags, his attitude can influence the development of the situation. Huang taiji's centralized efforts and the increasingly feudal Manchu society naturally let his eldest son, Hao Ge, participate in the competition. As far as interests are concerned, the ministers of the two yellow flags both hope that the prince will succeed to the throne in order to continue to maintain the dominant position of the two flags. In their view, Hogg's ability is higher because of his many military achievements. In the sixth year, Tiancong was promoted to Heshuo Baylor, and in the first year of Chongde, he was the prince of Jinsu, in charge of family affairs and on an equal footing with several uncles. When Huang taiji was alive, in order to strengthen centralization, he greatly weakened the strength of each flag, but at the same time maintained a certain strength and took the Zhenglan flag as his own. These three flags are far more powerful than other flags. Therefore, the representatives of these three flags must support Hogg's succession. Another competitor is Dourgen. Needless to say, his military and cultural talents are backed by two white flags and two brave brothers. Moreover, some royal families of Zhenghongqi, Zhenglanqi and Zhenghuangqi secretly supported him and made him more powerful. There is another person who can't be ignored, and he is the owner of the blue flag, Jill Harlan. Although he is unlikely to take part in the competition, his opposition has a great influence on other factions, and no matter which side he favors, it will tilt the balance of power.

To be fair, only three people are qualified to inherit the vacancy left by Huang Taiji: Dai Shan, Haug and Dourgen. But in fact, the most intense competition is the latter two. As far as these two people are concerned, Hogg is the eldest son, and his strength is slightly stronger, not only because he has three flags, but also because Daishan and JiErlang have already felt the aggressiveness of Dourgen, so they are ready to vote for Hogg.

Sure enough, shortly after Huang Taiji's death, both sides became active, and then changed from behind the scenes to the public.

Two ministers of the Yellow Flag, Toure, Sony, Tulai and the Western Han Dynasty, discussed the establishment of Haug, plotted for a long time, and found Jill Harlan to seek his support. The two princes with white flags, Archie and Dodo, also found Dourgen and expressed their support for his accession to the throne, telling him not to be afraid of the two ministers with yellow flags. There are frequent activities between the two sides, and the atmosphere is becoming increasingly tense. First, Turg, who put forward the idea of establishing Hauge, ordered his soldiers to draw their swords and draw their bows to protect their homes, just in case. On August 14 of that year, Wang got together in Chongzheng Hall to discuss the issue of succession to the throne. Whether this problem can be solved peacefully is directly related to the safety of the Eight Banners and the future of the Qing Dynasty. The two yellow flag ministers can't wait. On the one hand, they sent people to be nervous and surrounded the Chongzheng Hall. On the other hand, holding the hilt, he broke into the main hall and took the lead in advocating the establishment of a prince, but was denounced by Dourgen as illegal. At this time, Azig and Dodo later came out to persuade Dourgen to accede to the throne, but Dourgen observed the situation and did not agree immediately. Duoduo turned to Daishan as a candidate, while Daishan argued on the grounds of "old age and infirmity" and proposed Dourgen and Haug, with ambiguous opinions. Seeing that he could not pass the customs smoothly, Haug threatened to leave. The two ministers of the yellow flag also left their seats, pressed their swords forward and said, "If you don't set up a prince, you'd rather die than go underground from the first emperor!" Daishan saw the great potential and hurriedly quit, followed by Archie. When Dourgen saw this situation, he felt that he could not stand on his own feet as emperor. He quickly put forward his opinion that Fu Lin, the youngest son of Huang Taiji, should be emperor, and he and JiErlang should be able to make ends meet, and then return to politics when he is old. This proposal surprised everyone. As soon as the prince was established, the mouths of the two yellow flag ministers were blocked. Hogg was unhappy, but he couldn't say it. Dourgen made a step forward by retreating, but as an assistant king, he was also the actual ruler. Gil Haran himself didn't expect to touch the light, and of course he wouldn't object. Dai Shan only wants the overall situation to be stable, and has no desire to fight for a position, and has no objection to this plan. In this way, this compromise is accepted by all parties, but the resulting new political pattern will have a great impact on the political situation in the next few years or even decades. Dourgen chose Fu Lin as emperor because some poets and poets dragged him into the "love" with his mother, Zhuangfei. In fact, Dourgen chose Fu Lin because he was only six years old and easy to control, and ruled out Haug, thus excluding Ye Bushu and his ministers. Second, because his mother, Princess Yongfu Gongzhuang, won the favor of Huang Taiji and had a high status, ministers were more likely to accept her son as emperor, even in line with the wishes of the first emperor. Of course, although the name of the imperial concubine of Lin Zhigong is higher than that of Zhuang Fei, her actual status is not high, and her two-year-old son, Baimu Bogor, cannot be selected. At the same time, the candidate for the assistant king also represents the balance of power of all parties. Since the Yellow Flag and the White Flag are the main competitors, Fu Lin's accession to the throne has already represented the interests of the Yellow Flag and Zhenglan Banner, and it is inevitable that Dourgen will be the assistant government. But I was afraid that he would not get the consent of his opponent when he came to power alone, so I pulled Jilalang. In the other side's view, this is a centrist who suppresses Dourgen. In Dourgen's view, this man is easier to deal with. For the lower subjects, Dourgen and Jill Harlan were the most trusted and reused people in Huang Taiji's later years. They took the lead in handling many government affairs, so it is not surprising that they became regents.

In this way, Dourgen properly handled the very thorny issue of the struggle for the throne, and he himself took a step toward the peak of power. Subsequently, the ruling group dealt with Ailidu, Shuogui, Houge and their subordinates who opposed this new pattern, and stabilized the new rule. This plan of Dourgen objectively avoided the civil strife in the Eight Banners, preserved its strength and maintained the basic consistency of the upper ruling group. Of course, his proposal was put forward after his struggle for the throne was not easy to succeed. It was put forward under the threat of two ministers with yellow flags, not because he was far-sighted and broad-minded from the beginning.
