Is it Xia's daughter after all?

Of course it is! There are vows of summer, words of summer, and I know summer like the back of my hand.

If it weren't for Xia's daughter, Xia wouldn't let him go to Beijing to find it.

As for what Qianlong said, because they let ChristianRandPhillips go, and the queen fanned the flames, they found clothes from Huibin Building.

The Queen also found Wei Zi's uncle and aunt from her hometown in Jinan and bribed them to frame Wei Zi, saying that Wei Zi was not the daughter of Qianlong.

That's why Ganlong said that, because he was angry.

I hope I can help you ~
