The Qing Dynasty was the last feudal dynasty in China and a very special dynasty. Let's say that the temple numbers of the emperors of the Qing Dynasty actually appeared three ancestors, namely the Qing Taizu Nur Hachi, the Qing Dynasty Zu Fu Lin, and the Qing Shengzu Xuan ye.

Is there a problem with the emergence of three ancestors in a dynasty? According to previous dynasties, the founding emperor of a dynasty was called Taizu or Gaozu, followed by Zong, taking the Tang Dynasty as an example, Gaozu was Li Yuan, Taizong was Li Shimin, and later emperors were zong. The same was true of the Song Dynasty, taizu was Zhao Kuangyin, and Taizong was Zhao Guangyi.
So is there something special about it? There are still some. For example, the Taizu of the Yuan Dynasty was Genghis Khan Temujin, the ancestor of the Yuan Dynasty, Kublai Khan, and the emperor of the later generations was called Zong. The Ming Dynasty Taizu was Zhu Yuanzhang, and the Ming Chengzu was Zhu Di, but there were no three ancestors like the Qing Dynasty.
First of all, it should be clear that Taizu and Taizong are temple numbers, which are given by the emperor's descendants after his death, and their temple numbers are an affirmation of the emperor's life's achievements. Taizu and Gaozu had pioneering merits, so they were generally founding emperors. Kublai Khan, the ancestor of the Yuan dynasty, unified the whole country and established the Yuan Dynasty, and it is also possible to call the ancestor.
Emperor Yongle of the Ming Dynasty was Emperor Taizong of The Ming Dynasty before Jiajing. The Jiajing Emperor, in order to give his father the title of King Xingxian, changed Emperor Taizong to Ming Chengzu. Of course, Ming Chengzu Zhu Di made five conquests of Mongolia in his lifetime, moved the capital to Beijing, and Zheng He went to the West, and his meritorious deeds were called ancestors and no one said anything.
Speaking of the Qing Dynasty, although the Nurhaci period was called Jin (Later Jin), it did not unify the whole country, at least it had the merit of creation, so it was called Taizu. Nurhaci was followed by Emperor Taiji, whose temple name was Taizong, and theoretically the subsequent emperors should also be Emperors.
In fact, Emperor Taiji was the founder of the Qing Dynasty, and after the Change of Jin to Qing, the basic system of the early Qing Dynasty was established. He was born at the wrong time, and his life shrank north of Shanhaiguan, and finally let his son Fu Lin pick up the cheap.
Fu Lin can be called Shizu because when he was emperor, he caught up with the late Ming Dynasty king to enter Beijing, and the Qing Dynasty took advantage of the fire to rob and move the capital to Beijing (1644). During the Shunzhi Dynasty (Fulin), national unification was basically realized. But Fu Lin's time as emperor was too short, he ascended the throne at the age of 5, served as emperor for 18 years, and hung up at the age of 24 (1661).
The Shunzhi Emperor was the regent of Dolgun in the early stage, and basically did not care about anything in the later period, but left a mess for his son. When the Kangxi Emperor (Xuan Ye) ascended the throne, there were tsarist Russia on the outside, the Northwest Jungar Department rose in the steppe, and there were a series of crises such as the Hidden Dangers of San Francisco and the Remnant Party of the Ming Dynasty.
It should be known that Kangxi was only 8 years old when he succeeded to the throne, which was the time when the lord was suspicious of the country, but Kangxi still relied on his ability, of course, it was inseparable from other factors such as the assistance of the sages, he was pro-government at the age of 14, and he got rid of Aobai at the age of 16. Then later to recover Taiwan, sign the Treaty of Nebuchu with Russia, defeat Dzungar, and recover Taiwan, so that the Qing Dynasty can be stabilized.
In terms of governing the country, it attached great importance to Confucianism, opened the imperial examination, learned Hong Confucian science, etc.; built water conservancy, paid attention to farming, and in order to reduce the burden on the people, Kangxi announced in the fifty-first year that it would never increase the endowment and promote population growth. Such merit, in Yongzheng's view, is completely without problems in being called the Holy Lord. However, the emperors after Kangxi, even qianlong, who were very happy and meritorious, his temple name was only Gaozong.
Back to the title question, Qing Taizu Nur Hachi, Qing Shi Zu Fu Lin, Qing Sheng Zu Xuan Ye, who has the most moisture, presumably the reader already has his own answer in his heart.
