According to legend, Bukuri Yongshun, the ancestor of Aisin Kyora, was born near Changbai Mountain, and the city of Orori that he started is today's Dunhua. Jueluo is a place name in the Yilan area of Heilongjiang Province. If Nurhaci's surname is Aisin Kyora, then the theory of Bukuri Yongshun's ancestors is problematic. This raises the question, what is Nurhaci's last name?
First of all, let's talk about the origin of Aisin Kyora. The Jurchens did not value surnames and used tribal names as surnames. The ancestral surname of the Aisin Jueluo clan is Jiagu, which belongs to the Aixin tribe, and because the tribe is a distant branch, the two are combined into one, resulting in aixin jueluo. Emperor Taiji established the country, imitating the Han system, abolishing the distinction between Dazong and Yuanzhi, and Aixin Jueluo became an independent surname. This is also the most commonly used explanation of Nurhaci's surname Aishin Kyora.
Nurhaci's surname "Tong" and "Tong" derive from the historical records of Korea and the Ming Dynasty. Nurhaci once inherited his father's official, and repeatedly paid tribute to the Wanli Emperor as the commander of the Jianzhou Left Guard, and the Ming Dynasty has a large number of records of this, all of which indicate that Nurhaci's surname is Tong. Shin Chung, the master of southern Korea, wrote in the "Chronicle of The Chronicle of Jianzhou": In the first month of the twenty-fourth year of the Wanli calendar, Nurhaci's reply to the King of Joseon wrote the words "Tong Nurhaci, the lord of the Jurchen Kingdom's Jianzhou Wei guan Shu Yiren".
Whether it is Tong or Tong, both are Han surnames, and Zhang Binglin believes in the "Qing Jianguo Bie" that the Jurchens calling themselves han surnames are avoiding their identity as ethnic minorities.
In addition to Tong and Tong, in The Literature of North Korea, there is also the surname Choe. However, modern scholars have found that Cui may be a misreading of Jue Luo. Choe's pronunciation in Korean, between Lack and Blowing in Chinese, is very similar to Kyaw Lo's Kyaw pronunciation.
In some historical sources, it is recorded that nurhaci VI's ancestor, the fierce brother Timur surnamed Jin, aixin if translated by transliteration, it is also Jin.
So far, nurhaci's surname Aishin Kyora is more accepted, but it does not mean that several other theories are wrong, according to the available information, the surname Aishin Kyora can not be conclusive.
