Princess Zhu Huan Part II Kangkang is no longer a child. Whose daughter is it?

In Princess Zhu Huan, Erkang said to Wei Zi: No matter you are poor or rich, no matter whose daughter you are, I love you.

One of Wei Zi's most important identities is the illegitimate daughter of Emperor Qianlong. Ganlong traveled eastward and met Xia. Xia was gentle and eloquent, which made Ganlong fall in love at first sight, so he was lucky that night, but Ganlong did not take him into the harem, but stayed in Jinan. Unexpectedly, Xia Yuhe was pregnant with the flesh and blood of Qianlong and gave birth to Wei Zi Gege.
