Gan Long, is it Han or Manchu?

It should be full of people, but there is a folk saying that he is the son of Chen Ge, an old man in Haining, and it is also based on this incident in Jin Yong's novel "The Sword, The Record of Life and Hatred". But it's hard to say who's right or wrong. However, I think that in any case, Manchu people have a strong sense of ethnicity, and there must be a Manchu who can't marry. So I think even if Yongzheng did everything for the throne, he still had two other children at that time. Although one child is stupid, there is still an old 2 macro who can be a great leader if he wants to train carefully.
