What constellation is Guo Bibi _ What constellation is Guo Beibei?

What does Gemini mean in literary world? Why is it called Gemini?

I don't think it means their horoscope.

It should be that their styles are similar, but they are developing in different fields.

Both of them are great, and their fields complement each other, so they are called Gemini.

Kind of like Shuang Jie in the literary world.

I hope it can be adopted. Thank you.
