Why did Erkang, the first part of Princess Huanzhu, say that Wei Zi was Zhuge?

It was taken by Ganlong. It should be because my daughter is the apple of my father's eye, and Wei Zi is Gege, so it is called Mingzhu Gege. It is also possible that Ji Xiaolan gave the Swallow a Pearl Princess, and Wei Zi is a real princess, so it is called Pearl Princess. This is also a metaphor.
