Is Erkang in Princess Pearl Fu Kangan? Is it Fu Heng's son?

Fuer Kang Sheng came to be a slave of Xiawuqi Coating, and his mother is a distant cousin of your princess.

To put it bluntly, he is a slave. Poof!

Fu Kang 'an was a noble with three banners, and his father Fu Heng was a college student, and he was also a brother of filial piety after Qianlong Yuan. He can also be said to be Qianlong's nephew.

Fu Kang 'an is a legendary figure who gave birth to Beizi and died in the county seat. He was deeply loved by Qianlong all his life and went to study. Unlike Bandu in Fourcand, unofficial history called him the illegitimate child of Qianlong.
