Xia Ziwei in Princess Zhu Huan is undoubtedly the daughter of Qianlong, but do other children of Qianlong have anything to do with Wei Zi?

Wei Zi and Yongqi are half-brothers. Their children are called Naner, and Dong Er is a cousin.

That is to say, Naner is called Aunt Wei Zi and Dong Er is called Uncle Yongji.

Cousins refer to grandparents with the same status, not brothers and sisters, that is, children of different sons in a family. Cousins call each other's father uncle according to their parents' age.

So the swallow is not Wei Zi's cousin.

In ancient times, aunts and cousins were normal, especially in the royal family.
