There is no record of Fu Erkang in history, including Fu Erkang's father Fallon, who is not a real person. Therefore, people have two kinds of guesses about Fu Erkang's prototype, one is that Fu Lingan is Fu Erkang's prototype, and the other is Fu Kangan. The speculation about Fu Lingan is the conclusion that Fu Erkang and Fu Lingan's life trajectories coincide. In history, Fu Ling 'an and Fu Erkang in film and television dramas were both forbidden soldiers and Xu in film and television dramas. Moreover, Fu Erkang in the film and television drama disappeared in Yunnan, and Fu Lingan in history died on the battlefield in Yunnan, so people will guess that Fu Erkang is Fu Lingan.
The statement that Fu Erkang is Fu Kang 'an actually comes from their names, but Fu Erkang and Fu Kang 'an have completely different life experiences, so it is hard to say that Fu Erkang is Fu Kang 'an, but Fu Kang 'an in unofficial history does have a life story. According to unofficial history's records, Qianlong took a fancy to Fu Cha's sister-in-law, that is, Fu Heng, the wife of his general Fu Cha, and repeatedly called her into the palace to commit adultery. Finally, Fu Heng's wife gave birth to Fu Kang 'an, and Fu Kang 'an's life experience became an unsolved mystery. So why is it so popular in unofficial history? This is because Qianlong loves Fu Kang 'an too much. Although Qianlong himself said that Fu Kang 'an was like the son of Tongfu Tea Queen, raising a nephew as a son really made people guess Fu Kang 'an's life experience. Whether Fu Kang 'an is the son of Qianlong remains to be verified.
Because the historical prototype of Fu Erkang is not Fu Kangan, there is no doubt about the life experience of the son of Qianlong in Fu Erkang.
