What does the girl mean by panda head?

Actually, it's nothing special, but maybe this girl likes pandas and thinks they are cute. Girls have no resistance to cute things, let alone pandas. Using a panda as an avatar can be seen that this girl is also a very cute and lovely girl.

Nothing else. The avatar doesn't mean anything. Many girls often change their avatars, but each avatar doesn't mean anything. In fact, they just feel so happy and want to change.
