What does "Faxi" mean in the picture of the twin princess?

Also known as: mysterious planet twin princess

Fache refers to Fayin and Hildur (FX for short)?

Princess Gemini is the protagonist in the cartoon. Fayin is the princess of Sun Country. This cartoon has a mainland version (Shun Zhe Fang Fang), a TVB version (Shane French sound) and a Japanese version (Hilde French sound). Supporters who want the red princess Fayin of the sun country to be with the prince Hildur of the moon country call this cp "Faxi"? Because the French pronunciation is red princess, it is also called "Moon Red", "Fa Xia" and "Fang Shun".

Dharma is French sound (Fangfang), and Xi is Hildur (Shunzhe). Together, they are called Faxi.

Foreign voice: Ah, I'm a fan of Fassi.
